Two pairs of amino-acid functionalized poly(3,4-ethylenedioxythiophene) (PEDOT) derivatives, namely, poly( N -(tert-butoxycarbonyl)- L -methionyl (3,4-ethylenedioxythiophene-2’-yl)methylamide) ( L -PEDOT-Boc-Met) and poly( N -(tert-butoxycarbonyl)- D -methionyl (3,4-ethylenedioxythiophene-2’-yl)methylamide) ( D -PEDOT-Boc-Met); poly( L -methionyl (3,4-ethylenedioxythiophene-2’-yl)methylamide) ( L -PEDOT-Met) and poly( D -methionyl (3,4-ethylenedioxythiophene-2’-yl)methylamide) ( D -PEDOT-Met) were synthesized via chemical oxidative polymerization of corresponding monomers. The structural characterization, spectroscopic properties and thermal stability of these monomers and polymers were systematically explored by FTIR spectra, Raman spectra, XRD spectra, UV-Vis spectra and thermogravimetric analysis. As chiral electrode materials, these polymers were employed to successfully recognize 3,4-dihydroxyphenylalanine (DOPA) enantiomers by cyclic voltammetry (CV) in sulphuric acid solution. The measurement results reveal that the tendency was hetero-chiral interaction between L -PEDOT-Met/PVA/GCE and D -DOPA, D -PEDOT-Met/PVA/GCE and L -DOPA, respectively. Also, the mechanism of chiral discrimination was discussed. All the results implied that the combination of electrochemical molecular recognition technology and chiral PEDOT materials can be a promising approach for chiral recognition and may open new opportunities for facile, biocompatible, sensitive and robust chiral assays in biochemical applications.

Sb 2 Se 3 has appeared as a highly prospective anode material for lithium-ion batteries (LIBs) owing to its abundant resources, a remarkable theoretical capacity of 670 mA h g −1 , and the presence of both alloy and conversion reaction mechanisms. Nevertheless, its drastic volume change during cycling caused rapid capacity decay. To address these issues, a common approach is to combine Sb 2 Se 3 with carbon materials. In this study, Sb 2 Se 3 encapsulated in multi-walled carbon nanotubes (MWCNTs) were fabricated through a one-step low-pressure vapor-phase reaction, forming the Sb 2 Se 3 @MWCNTs composite. The nanosize effect of Sb 2 Se 3 can alleviate its structural fracture during cycling. MWCNT network is advantageous for electron/ion transport. Subsequently, poly(3,4-ethylenedioxythiophene) (PEDOT), a conjugated polymer, was employed as an electron-enhancing buffer layer to further coat MWCNTs, creating the Sb 2 Se 3 @MWCNTs/PEDOT. More importantly, the PEDOT layer could create a robust solid electrolyte interface (SEI). By adjusting the ratio of Sb 2 Se 3 to MWCNTs, Sb 2 Se 3 @MWCNTs/PEDOT-7:3 composite exhibited a capacity of 648 mAh g −1 after 200 cycles at 0.5 A g −1 and a capacity of 495 mAh g −1 after 970 cycles at 2 A g −1 , demonstrating a highly promising class of high-performance LIB anode materials.

Herein, an enhanced lectrochemiluminescence (ECL) immunosensor was designed based on an efficient ECL bioprobe and first realized the quantitative analysis of human epididymis protein 4 (HE4). To obtain the efficient ECL bioprobe, a self-assembled mesocrystalline hybrid (TiO 2 MCs@rGO) was first prepared for loading luminol and 2-(Dibutylamino)ethanol (DBAE), which was explored as a new coreacant of luminol for the first time and triggered more stable and efficient ECL intensity than conventional luminol-H 2 O 2 system. Additionally, the high surface area and outstanding conductivity of TiO 2 MCs@rGO would effectively amplify the ECL intensity. Besides, the synthesized macromolecular complex (PEDOT/PSS/NiCo 2 O 4 NS) integrated the excellent conductivity of PEDOT/PSS and highly porous of NiCo 2 O 4 nanosheets was served as an efficient sensing matrix for further improvement of the analysis sensitivity. The developed ECL immunosensor exhibited excellent performance in the analysis of HE4 with a wide linear range of 1.0 × 10 −5 ˜1000 ng/mL and low detection limit of 3.3 × 10 −6 ng/mL, especially superior stability. The strategy provided promising application for early ovarian cancer monitor and diagnosis, and provoked a new idea for other tumor markers detection.

Electrochromic devices are emerging as a futuristic technology for flexible electronics with the practical application values in energy-saving, displaying and military camouflage, however, the limitations in the optical, electrical and mechanical properties of the existing transparent conducting electrodes (TCEs) appear as a major obstacle for realizing high performance flexible electrochromic devices. In this work, we have proposed and demonstrated a fast-response and bendable polymer poly (3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT: PSS) electrochromic device based on the embedded nickel (Ni) grid electrode. The Ni grid electrode, fabricated though patterned electroplating, has low sheet resistance (~1.3 Ω/sq), high transparency (~80%), excellent mechanical reliability and long-term chemical stability, exhibiting a figure of merit of 1250, surpassing the most existing TCEs. In addition, we have proposed a compact electrochromic architecture with the electrochromic PEDOT: PSS layer and solid polymer electrolyte being sandwiched between two embedded Ni grid electrodes. The device shows a short coloration and bleaching time (~1 s for 90% optical contrast), a high coloration efficiency (325 cm 2 /C) and excellent mechanical reliability (optical contrast retention ~80% after 1000 bending circles), paving a way for high performance flexible electronics.

Ammonium vanadate (NH 4 V 4 O 10 ) is supposed to be the most potential cathode candidates for aqueous zinc ion batteries (AZIBs) due to its stable layered structure and high theoretical capacity. However, the strong electrostatic interaction between Zn 2+ and NH 4 V 4 O 10 lattice impede its further application. Herein, an efficient hydrothermal method was used to synthesize poly(3, 4-ethylenedioxythiophene) pre-intercalated NH 4 V 4 O 10 (NVO-PEDOT), which shows promising Zn 2+ storage properties as a cathode material for AZIBs. The NVO-PEDOT presents flower-like morphology composed of nanoribbons, which can shorten Zn 2+ diffusion path. Moreover, the pre-intercalated PEDOT introduces oxygen vacancies and low valence vanadium, which not only weaken electrostatic interaction between Zn 2+ and NH 4 V 4 O 10 , but also enhance electronic conductivity, promoting the reversibility of NH 4 V 4 O 10 toward the de−/intercalation of Zn 2+ . Accordingly, NVO-PEDOT cathode provides high reversible capacity (381 mA h g −1 at 0.1 A g −1 after 87 cycles), excellent rate capability (130 mA h g −1 at 20 A g −1 ) and long-life cycling (105 mA h g −1 after 1500 cycles at 10 A g −1 ), confirming the effective synthesis strategy of NH 4 V 4 O 10 cathode for high performance AZIBs.

In all-perovskite tandem solar cells (TSCs), thick (>1 µm) Sn-Pb rear sub-cells suffer from hole accumulation-driven Sn 2+ photo-oxidation due to unbalanced charge transport. Traditional sacrificial reductive additives fail to address this photo-stability challenge. Herein, we employ a low-temperature solution-processed solid-state polymerization (SSP) method using 2,5-dibromo-3,4-ethylenedioxythiophene (DBEDOT) to in situ construct poly(3,4-ethylenedioxythiophene) (PEDOT) hole transport channels within the perovskite film. This approach enhances hole extraction, therefore balancing electron-hole transport in Sn-Pb rear sub-cells as well as recombination between two sub-cells. Consequently, we achieve a 24.20% power conversion efficiency (PCE) for single-junction Sn-Pb devices and a 29.58% PCE for all-perovskite TSCs. Significantly, by suppressing Sn 2+ photo-oxidation through mitigated hole accumulation, the tandem device retains 90% of its initial efficiency after 1100 h of continuous operation at 55°C under maximum power point (MPP) conditions. This strategy offers a promising route toward the development of highly efficient and stable all-perovskite tandem photovoltaics.

A PEDOT-MOF/polypeptide modified multi-modal micro-ECoG electrode is proposed. • PEDOT-MOF achieves dual functions of ROS sensing and efficient scavenging. • Polypeptide/DEX enhances electrode biocompatibility and reduces inflammation. • In vivo validation of multi-modal ECoG/ROS recording and immunomodulation The limited biocompatibility of conventional flexible electrode materials often triggers host immune responses, manifesting as glial encapsulation and the overproduction of reactive oxygen species (ROS). Meanwhile, ROS accumulation further exacerbates local inflammation and induces irreversible cellular damage. Therefore, constructing a highly biocompatible electrode-tissue interface and developing multi-modal microelectrodes capable of recording and regulating in-vivo ROS concentrations are critical for alleviating immune responses and clarifying the underlying mechanisms of electrode failure. In this work, we proposed a novel modification strategy for micro-electrocorticography (micro-ECoG) electrodes to enable multi-modal neural recordings (ECoG and ROS) and regulations (drug deliver and ROS catalyze). For this purpose, the electrode surface is modified with Cu-metal-organic framework (Cu-MOF)-doped poly(3,4-ethylenedioxythiophene): polystyrenesulfonate (PEDOT:PSS), denoted as PEDOT-MOF. Additionally, a highly biocompatible polypeptide coating loaded with anti-inflammatory drugs is introduced to further suppress immune reactions. In vitro experiments reveal that PEDOT-MOF exhibits excellent electrochemical performance and detection sensitivity to H₂O₂, indicating its multifunctionality to catalyze the ROS for mitigating oxidative stress and monitor dynamic changes in ROS concentration in real time. In vivo implantation studies confirm that microelectrodes modified with the drug-loaded polypeptide coating exhibit lower interface impedance and higher SNR. Collectively, these results highlight the significant application potential of PEDOT-MOF-modified micro-ECoG electrodes combined with a drug-loaded polypeptide coating, which may address key challenges in current implantable neural electrode technology. It should be noted that, due to partial channel attenuation over chronic implantation and spatial diffusion effects of dexamethasone, this platform is more suited for monitoring relative ROS dynamic trends. Future optimizations will further advance the capability toward accurate in-vivo ROS absolute quantification.

Hydroxyl-functionalized MWCNs and PEDOT are better suited for loading MIP. • The sensor detects pefloxacin at the picomolar level. • Synthesis of ultra-thin tubular PEDOT-OH@Au/MWCNs-OH nanocomposites. • The excellent thin-layered structure offers an efficient electron transport pathway. To safeguard public health and prevent the increase of bacterial resistance, the creation of practical and accurate detection methods for the quantitative analysis of fluoroquinolone antibiotics is essential. In this study, a tubular PEDOT-OH@Au/MWCNTs-OH substrate material was prepared using a one-step in situ oxidation method, with chloroauric acid as the oxidant. Pyrrole (Py) was used as the functional monomer, and pefloxacin (PFX) as the template molecule, to ingeniously design a molecularly imprinted electrochemical sensor (MIP/PEDOT-OH@Au/MWCNT-OH) with sensitive sensing capabilities. As expected, the unique structure and properties of PEDOT-OH@Au/MWCNTs-OH provided the sensor more surface area and enhanced electrochemical activity, increasing the number of distinct recognition sites. Based on experimental results, the MIP/PEDOT-OH@Au/MWCNT-OH sensor showed good anti-interference and stability, a low detection limit of 0.149 nM, S/N = 3, and a broad linear range of 0.002–30 μM. Additionally, the sensor achieved a recovery rate of 97%–103% in detecting PFX in pefloxacin mesylate ointment. This sensor shows promise as a highly selective and sensitive portable detection method for the quantitative analysis of PFX in the environmental monitoring.

Poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT: PSS) is a widely used hole transport material in tin-lead perovskite solar cells, yet its photoelectric properties require further enhancement. Herein, we develop a rational gradient doping strategy using DL-carnitine hydrochloride (DL-ChCl) to regulate PEDOT: PSS and improve its buried interface with the tin-lead perovskite. The DL-ChCl induces high p-type doping in PEDOT: PSS, resulting in enhanced conductivity and an elevated work function for improved hole extraction via favorable energy level alignment. Simultaneously, the crystallization quality of the tin-lead perovskite is also enhanced by hindering Sn 2+ oxidation, passivating interfacial defects, and preventing the formation of lead iodide. As a result, a champion power conversion efficiency of the inverted tin-lead perovskite solar cell is enhanced from 18.56% to 21.23% with the open-circuit voltage as high as 0.865 V. The stability of the optimized device without encapsulation is also improved, sustaining 90% of its initial efficiency after aging in a nitrogen atmosphere for 1200 h. This work provides an effective gradient doping strategy to engineer the buried interface between PEDOT: PSS and tin-lead perovskite, improving the photovoltaic performance of tin-lead perovskite solar cells.

Microcellular polymer composites with an excellent conductivity are greatly desired for electromagnetic interference (EMI) shielding applications, but it still remains a great challenge to fabricate conductive composite foams with intelligent EMI shielding performance at minimal amounts of functional filler. Herein, a novel and facile technology is developed for in-situ creating poly(3,4-ethylenedioxythiophene)/ferroferric oxide (PEDOT/Fe 3 O 4 ) in the closed-cells of bulk epoxy foams without sacrificing the lightweight and mechanical properties. Via vapor phase polymerization of EDOT monomer using FeCl 3 as oxidant and followed by alkali treatment, the in-situ generated PEDOT/Fe 3 O 4 composites densely pack at the inner walls of closed-cells to form the highly conductive islands. These islands are linked by the nanofiller/PEDOT conductive chains in cell walls, thus constructing the unique “island-chain” segregated conductive nanostructure. This architecture endows the resultant composite foams with good conductivity, outstanding EMI shielding effectiveness, highly effective absorbance (A eff ), epsilon-negative (ε′ < 0) response and considerable compressive strength, showcasing obvious advantages as compared to conventional design in open-cells. Moreover, these functional composite foams display a repeatably pH-sensitive EMI shielding performance with a significant difference of 14 dB, providing a potential approach for intelligent EMI shielding.

Elevated cholesterol is a major cardiovascular risk factor, but current detection methods are resource-intensive. Non-invasive point-of-care testing is promising yet limited by sensitivity, and the blood-saliva cholesterol correlation requires further investigation. We developed an electrochemical biosensor featuring cholesterol oxidase immobilized on screen-printed carbon electrodes (SPCE) modified with conductive Au-Ag@Au core-shell nanoparticles and Prussian blue/poly-3,4-ethylenedioxythiophene (PB-PEDOT) nanocomposites. Morphological, spectroscopic, and electrochemical analyses (including impedance spectroscopy, heterogeneous electron transfer kinetics, and active surface area quantification) confirmed the biosensor superior conductivity. The biosensor achieved exceptional performance: a broad linear range (0.01–1.0 mM), low detection limit (3.3 μM amperometric LOD; 2.8 μM via EIS), and high sensitivity (57.3 μA/mM·cm 2 amperometric; 781 Ω/mM·cm 2 impedimetric). Clinical validation demonstrated excellent agreement with standard colorimetric methods in human serum and saliva for cholesterol tested in biological compounds and robust stability. A strong serum-saliva correlation (Pearson's correlation coefficient as 0.928) supports noninvasive monitoring feasibility. The anti-interference capability of the proposed biosensor was evaluated against common interferents, including glucose, lactic acid, uric acid, ascorbic acid, bovine serum albumin, cysteine, and their mixture. The results confirmed its high specificity against these typical biological matrix components. Particularly significant is its non-invasive detection capability, which eliminates the need for painful blood draws or invasive sample collection procedures. A key innovation lies in the synergistic integration of conductive Au-Ag@Au core-shell nanoparticles with PB-PEDOT nanocomposites on SPCEs, which significantly enhances electron transfer and catalytic activity, yielding an exceptionally sensitive and stable sensing platform. The biosensor sets itself apart by achieving superior analytical performance concurrently with robust clinical validation in both serum and saliva, firmly establishing its potential for reliable non-invasive cholesterol monitoring.

A conducting polymer based composite material of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with pure insoluble ionic liquid (IL), 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, was prepared through a cost-effective electrodeposition method. A very tiny amount of insoluble IL (less than 15 μL), containing 0.1 M conducting polymer monomer, was drop-coated on an electrode surface and then used for electropolymerization using a homemade electrochemical cell filled with aqueous supporting electrolyte. With this design, the consumption of expensive IL for the preparation of the PEDOT/IL composite was greatly reduced, and thus effectively reduced the cost. The prepared PEDOT/IL composite was found to be highly conductive and stable, and it exhibited a highly nanoporous microstructure and excellent electrocatalytic activity toward the oxidation of dopamine (DA). Based on the excellent stability and electrocatalytic activity of the PEDOT/IL nanocomposite, a highly stable, sensitive and selective DA sensor with a detection limit of about 51 nM was developed.
