Organic cathode materials have garnered significant attention for their potential application in lithium-ion batteries due to their lightweight nature, tunable structures, high energy density, and environmental friendliness. However, the dissolution of organic cathodes in liquid electrolytes often leads to poor cycling stability, which limits their practical application. In this study, a composite cathode was prepared by ball milling the PTCDA/CuS (perylene-3,4,9,10-tetracarboxylic dianhydride, PTCDA) with a sulfide-based electrolyte and carbon nanotubes. By optimizing the component ratios, the assembled all-solid-state batteries (ASSBs) show a high discharge capacity of 210 mA⸱h/g after 200 cycles without any capacity degradation at a current density of 33.0 mA/g. Through comprehensive characterization techniques including X-ray diffraction (XRD), Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS), the coordination of Cu 2+ and the formation of sulfur-linked polymers during the charge-discharge processes are elucidated, and the reversibility of the electrochemical reactions has been confirmed. This work highlights the excellent compatibility between organic cathodes and sulfide-based electrolytes, providing a new way for the development of high-performance ASSBs with high energy density and extended lifespan.

Due to the different electron affinity, the construction of a donor-acceptor (DA) system in the graphitic carbon nitride (g-CN) matrix is an attractive tactic to accelerate photo-induced electron-holes separation, and then further elevate its photocatalytic performance. In this work, perylene tetracarboxylic dianhydride (PTCDA) with magnificent electron affinity and excellent thermal stability was chosen to copolymerize with urea via facile one-pot thermal copolymerization to fabricate g-CN-PTCDA equipped with DA structures. The specific surface area of g-CN-PTCDA would be enlarged and the visible light absorption range would be broadened simultaneously when adopting this copolymerization strategy. A series of characterizations such as electron paramagnetic resonance (EPR), steady and transient photoluminescence spectra (PL), electrochemical impedance spectroscopy (EIS), and photocurrent tests combined with computational simulation confirmed the charge separation and transfer efficiency dramatically improved due to the DA structures construction. When 0.25% wt PTCDA was introduced, the CO evolution rate was nearly 23 times than that of pristine g-CN. The CO evolution rate could reach up to 87.2 μmol g−1h−1when certain Co2+was added as co-catalytic centers. Meanwhile, g-CN-1 mg PTCDA-Co exhibited excellent long-term stability and recyclability as a heterogeneous photocatalyst. This research may shed light on designing more effective DA structures for solar-to-energy conversion by CO2reduction.Keywords:donor-acceptor;graphitic carbon nitride;PTCDA;photocatalysis;CO2reduction

Flower-like zinc oxide nanoclusters were successfully incorporated by different amount of PTCDA organic dye molecular, forming the hetero-structured PTCDA/ZnO composites. Remarkably, a study performed on their NO 2 sensing properties reveals that the 0.5 wt% PTCDA-loaded ZnO sensor exhibits high response, excellent selectivity, quick response speed and low detection limit of 7.4 ppb towards NO 2 molecules at room temperature (25 °C) under green light illumination, which possesses an apparent advantage over the ZnO sensors loaded with other PTCDA concentration as well as upon other light illumination conditions . This work makes a meaningful contribution to the development of NO 2 sensor based on wide-band gap semiconductors with visible light irradiation .

A three-dimensional composite carbon material (CNT@MPC) showing coaxial cable-like structure was prepared by carbon nanotubes (CNTs) and glucose through hydrothermal method . The ternary composite (PTCDA/CNT@MPC) was synthesized by coating a layer of 3,4,9,10-perylene tetracarboxylic dianhydride (PTCDA) molecules on the surface of CNT@MPC composite carbon material. The sodium ion battery was assembled using the ternary composite as the positive electrode material, and sodium metal as the negative electrode . The results show that the electrochemical performance of PTCDA/CNT@MPC composite is much better than that of pure PTCDA. The first discharge capacity is 131.2 mAh g −1 as the current density is 0.1 A g −1 , which is close to its theoretical specific capacity of 135 mAh g −1 . In particular, the battery shows better discharge properties at higher discharge current rate. When the current density reaches 10 A g −1 , the PTCDA/CNT@MPC electrode material is still able to attain a superior capacity of 90.1 mAh g −1 . This is due to the higher conductivity of CNT@MPC composite carbon material, which not only enhances the conductivity of PTCDA, but also increases the transport channel of ions, so as to increase the adsorption of sodium ions into the composite positive electrode. Therefore, the reversible capacity and cycle life of the composite electrode are significantly improved, which exhibit the excellent intercalation and de-intercalation performance for sodium ions and the charge-discharge rate performance.

Cu 2 O nanowire mesocrystals (NWMCs), which possess well-defined octahedral morphology and high-porosity architecture with anisotropic interpenetrating nanowires, have attracted considerable attention owing to their superior physical and chemical properties. However, the current synthetic approach for Cu 2 O NWMCs using graphene oxide as modifier leads to uncontrollable products and low productivity (~30 %), which largely hinder their further industrial application. Herein, we report a modified synthetic approach for controllable and large-scale preparation of Cu 2 O NWMCs using perylene-3,4,9,10-tetracarboxylic dianhydride molecule as modifier. The effects of growth time and initial pH on the morphology of final products have been systemically investigated. Under the optimal reaction condition with initial pH of 5.3 and reaction time of 15 h, the well-defined octahedral Cu 2 O NWMCs can be obtained with a productivity as high as ~75 %. In addition, this synthetic approach can be easily scaled up from 50 to 500 mL autoclave. The ability of high productivity and reproducibility in synthesis of Cu 2 O NWMCs enable us to further study their peroxidase-like activity by catalyzing the oxidation of o -phenylenediamine in the presence of H 2 O 2 . The Cu 2 O NWMCs have exhibited a superior catalytic activity with the K
cat of 1.14 × 10 −2 , 10 times higher than that of horseradish peroxidase. Moreover, the Cu 2 O NWMCs can also retain 69.5 % of their initial activities after 10-batch redox reactions. Our results provide a facile approach to controllable and large-scale synthesis of Cu 2 O NWMCs using homogeneous molecule modifier and open up opportunities to use Cu 2 O NWMCs as nanozyme for future industrial application.

Exploiting highly-efficient, broad-spectrum responsive and noble-metal-free water oxidation photocatalyst is a major challenge in the field of photocatalysis. Herein, we tackle this challenge by synthesizing Z-scheme PTCDA/g-C 3 N 4 photocatalysts, which can absorb light with wavelength short than 600 nm, for visible light photocatalytic O 2 production from water. Owing to the evident conduction and valance band energy level difference between PTCDA and g-C 3 N 4 , the PTCDA/g-C 3 N 4 photocatalysts exhibit efficient charge carrier separation through a Z-scheme mechanism, as demonstrated by the transient photocurrent responses and time-resolved fluorescence decay spectra analysis. Benefitting from the synergetic effect of the broad visible light absorption capacity and efficient charge separation, the optimized PTCDA/g-C 3 N 4 photocatalyst shows the highest O 2 evolution rate of 847 μmol·h −1 ·g −1 under visible light irradiation in the presence of Co 3 O 4 as a cocatalyst and AgNO 3 as the sacrificial reagent. An apparent quantum yield of 4.5% was achieved under monochromatic light irradiation at 420 nm.

The development of novel metal-free catalysts to photosynthesize hydrogen peroxide (H 2 O 2 ) is recognized as a prospective technology for sustainable energy conversion. Herein, the carbon-doped boron nitride (BCN) and perylene tetracarboxylic dianhydride (PTCDA) formed PDA@BCN S-scheme heterojunctions with π-π stacking, which catalyzed the production of H 2 O 2 at an unexpectedly high yield of 285.47 μmol h −1 g −1 in air. The high photocatalytic performance is attributed to the enhanced light absorption resulting in abundant carrier excitation, rapid charge separation driven by S-scheme heterojunctions, and highly selective H 2 O 2 formation pathway. Theoretical calculations demonstrate that carbon sites in PDA@BCN can serve as an advanced active center for oxygen enrichment and activation, promoting oxygen reduction and efficient photocatalytic production of H 2 O 2 . This work lays the foundation for the design of efficient, stable, and reusable photocatalysts for environmental restoration and energy conversion.

Flame retardant polyamide 6 (PA6) composites (PA6/PTCDA) were prepared by in situ polymerization of caprolactam with adding 0.01–2.5 wt% perylene-3,4,9,10-tetracar-boxylic dianhydride (PTCDA). The structure and properties of PA6/PTCDA composites were studied by Fourier transform infrared spectroscopy, X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, thermal conductivity, and limiting oxygen index (LOI) measurements. The results indicated that the crystallization of the PA6 chains was suppressed with 2.5 wt% PTCDA, and the LOI of the composite was 29.5. At the same time, the addition of PTCDA made the composites form a coke layer in the process of combustion, protecting the flammable components from volatilization and enhanced the flame retardant performance of the composites. This indicated that the PA6/PTCDA composite prepared by in situ polymerization possessed good flame retardant properties.

Graphical A straightforward heat- treatment strategy is proposed to load 3,4,9,10-perylenetetracarboxylic dianhydride into the matrix of boric acid to produce powders with a near-unity quantum yield and tunable emission color from yellow to green. The confinement effect of boric acid is responsible for the high emission efficiency of products. Developing solid luminescent materials with a unity quantum yield and tunable emission color is promising, although it is still a difficult task. A straightforward heat-treatment method has been developed to load 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) into the matrix of boric acid (BA) to produce powders with a near-unity quantum yield and tunable emission color from yellow to green. Our results suggest that the emission of the powders originates from PTCDA, and the tunability of the emission color is caused by the hydrolysis of PTCDA in the alkaline environment. The near-unity quantum yield is attributed to the BA matrix, which confines PTCDA. In addition, the powder also shows excellent thermal stability that allows its application in light-emitting diodes. The above results are important for the development of solid-state luminescent materials for various applications, and also provide a clue for studying the emission properties of luminescent materials.

Combining the advantages of dual-ion batteries (DIBs) and sodium-ion batteries (SIBs), we herein develop a superior sodium-based dual-ion battery (Na-DIB) based on the PTCDA organic anode and ionic liquid (IL) electrolyte. The system shows the highest specific discharge capacity of 177 mAh g–1 at 0.5C and excellent capacity retention over 100% at 2C after 200 cycles. Notably, even at an ultrahigh rate of 20C, the battery still maintains a considerable capacity of 60 mAh g–1 with a coulombic efficiency (CE) close to 100 and 94% capacity retention after 1000 cycles. Moreover, the self-discharge of the system has been investigated and shown to have an extremely low value of 0.18% h–1. Consequently, this work presents an excellent Na-DIB system, which could be a promising candidate for large-scale applications.

Organic carbonyl compounds as electrode materials have exhibited promising candidates for application in next-generation aqueous rechargeable batteries. However, a primary concern that is poor cycling performance are still remains due to high solubility of discharge products, which greatly limits their broader application. Herein, we developed a strategy to enhance the cyclability of aqueous zinc-organic batteries (AZOBs) by the terminal imidization and lateral π-system extension of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA). This strategy resulted in a perylene-based imide derivative with larger π-conjugated structure (2PDI), significantly inhibiting the solubility in an aqueous electrolyte. As expected, 2PDI as cathode offered a discharge capacity of 72.8 mA h g −1 at a current density of 100 mA g −1 , and even retaining 99.4% capacity after ultralong 50 000 cycles at 3000 mA g −1 . Its mechanism of reversible co-insertion Zn 2+ /H + at the carbonyl site was verified via electrochemical tests and ex-suit characterizations. Moreover, density functional theory calculation (DFT) also revealed this co-insertion mechanism.

A new type of composite membrane was prepared through the vacuum filtration self-assembly, in which, graphene oxide (GO) was the basic material, and the horizontal insertion material is product of perylene-3, 4, 9, 10-tetracarboxylic dianhydride (PTCDA) and UiO-66-NH 2 (PTCDA-UiO-66-NH 2 ). The leading role of Π-Π conjugate, auxiliary effect of hydrogen bonding during membrane preparation have been confirmed through Fourier transform infrared spectroscopy (FTIR), UV–visible spectrophotometer, Raman spectroscopy, and X-ray diffraction (XRD). The prepared GO@PTCDA-UiO-66-NH 2 membrane had new nodular structure compared to GO membrane by scanning electron microscopy (SEM) and atomic force microscopy (AFM), which promoted the water transport. In addition, the insertion of PTCDA-UiO-66-NH 2 narrowed the actual filtration spacing between GO sheets, and PTCDA-UiO-66-NH 2 could also adsorbed dye laterally. Experiments showed that the permeance of GO@PTCDA-UiO-66-NH 2 membrane was 1.7 times of GO membrane, and the removal of methyl blue, congo red, crystal violet and disperse black 9 was close to 100%. Under extreme pH, high salt concentration and multiple recycling, its separation ability was still excellent. The GO@PTCDA-UiO-66-NH 2 membrane constituted a unique synergistic structure of vertical-screening and horizontal-adsorption, which successfully overcame the trade-off effect and obtained excellent stability of structure and performance. Therefore, GO@PTCDA-UiO-66-NH 2 membrane had great potential in practical applications.
