Herein, MoO3 nanowires (Fe–MoO3 NWs) along the [110] direction were successfully synthesized in the presence of Fe3+ cations. The Fe–MoO3 NWs present a large specific surface area of 174.7 m2 g−1 and rich surface –OH groups, and the possible formation mechanism of such a structure is due to the adsorption of Fe3+ cations toward non-(110) planes of MoO3 in solution with pH greater than its isoelectric point. The obtained Fe–MoO3 NWs show excellent and highly selective adsorption capacity toward quasi-phenothiazine dyes (methylene blue, toluidine blue, azure I, and acridine orange). The dye removal rate could reach 99% in 3 min, and the maximum adsorption capacity is up to 144.3 mg g−1 and the adsorption is up to 28.86 mg g−1 per minute, which is 11 times greater than that of pure MoO3 and far greater than that of the recently reported MoO3 nanostructures. This excellent selective adsorption performance of Fe–MoO3 NWs was mainly attributed to the enhanced chemical adsorption of quasi-phenothiazine dyes by rich surface –OH groups and Fe species through hydrogen bond and coordination bond adsorption with N and S, respectively, which was confirmed by adsorption isotherms and adsorption kinetics. These results suggest the potential application of Fe–MoO3 NWs in the field of water pollution treatment.

Multicolor electrochromic polymers have attracted great attention and interest owing to their potential applications in multicolor displays, intelligent electronic devices, and smart visualized sensors. Herein, we prepared new electrochromic polysiloxanes by chemically coupling oligoaniline groups with cathodically colouring viologen and/or anodically colouring phenothiazine groups, respectively. Due to the combined effect and synergistic effect of paired anodically colouring oligoaniline and cathodically colouring viologen, the resulting polysiloxane exhibits multicolor electrochromic behavior switching from purple to transparent grey, to light green, finally to blue. As the oligoaniline units coupled with anodically colouring phenothiazine groups, the resultant polysiloxane also demonstrates multicolor electrochromic behavior changing from transparent grey to light green, to gray-blue, to brown and finally black purple. Furthermore, good switching durability has also been revealed during the electrochromic measurements, because of their robust network molecular structure and covalent bonding to the substrate.

Mitochondria, the primary energy-producing organelles, critically regulate cellular activities. Their internal viscosity—a key microenvironmental parameter—directly affects material transport and energy conversion, with aberrant levels linked to disease pathogenesis. Most reported mitochondrial viscosity probes were susceptible to polar interference, resulting in insufficient specificity for viscosity detection. This study designed and developed a novel polar-insensitive fluorescent probe, Y-CN , based on a phenothiazine skeleton - a small molecular compound with excellent fluorescent properties. The experimental data revealed an excellent linear relationship (R 2 > 0.99) between Y-CN 's fluorescence intensity and viscosity over a wide range from 1.005 to 219 cP. When viscosity increased from 1.005 cP (aqueous buffer) to 219 cP, Y-CN demonstrated a dramatic 209-fold fluorescence amplification. Furthermore, the probe exhibited excellent selectivity, pH stability, and low toxicity. Moreover, Y-CN could detect viscosity changes induced by food thickeners. Y-CN successfully monitored dynamic changes in mitochondrial viscosity within live cells, providing a powerful tool for specific investigation of mitochondria-associated physiological and pathological processes, with significant potential for biological applications.

Phenothiazine derivatives, as sustainable cathode materials for batteries , show significant promise for large-scale electrical energy storage applications. However, the irreversibility of the sulfur redox active center severely limits their energy density and discharge voltage in rechargeable organic batteries . This study concentrates on identifying the potential side reactions that contribute to the irreversibility of phenothiazine-based materials. We propose a molecular design strategy that synergistically blocks the active site and extends the conjugation, markedly improving the electrochemical reversibility of these materials. Our findings reveal that phenothiazine derivatives can undergo two successive, one-electron redox reactions without interference from chemical bond rearrangement and reactive radicals. The assembled cells, utilizing lithium (Li) and sodium (Na) as anodes, display two distinct discharge plateaus at 3.3/3.9 V vs. Li + /Li and 3.1/3.7 V vs. Na + /Na, respectively, with nearly identical contributions from the nitrogen (N) and sulfur (S) redox centers. The phenothiazine derivatives designed via this strategy rank among the few phenothiazine-based organic electrode materials capable of achieving highly reversible, two-electron transfer redox reactions in organic batteries.

Electrochromic small molecules suffer from the difficult film processibility and serious dissolvability at their oxidation state, which greatly limit their applications in electrochromic areas. Here, well-defined electrochemical polymer structures, pCZ-FSQ and pCZ-FEQ, are obtained by taking advantage of the unique electrochemical dimerization of carbazole, and low redox-potential phenothiazine and phenoxazine groups are introduced as an electrochromic color-changing unit with the interruption of conjugation between them via an alkyl chain linkage. The obtained polymer films pCZ-FSQ and pCZ-FEQ are composed of the independent dimeric carbazole and organic small molecule units. Finally, they exhibit outstanding electrochromic properties with optical contrast of more than 50%, switching time of less than 1 s, excellent stability (over 500 cycles of optical stability), and ultrahigh coloration efficiency (276 cm 2 C −1 for pCZ-FSQ , 384 cm 2 C −1 for pCZ-FEQ). This is thought to be greatly attributed to the well-defined electrochemical polymer structures with dual electrochromic color-changing properties of both phenothiazine/phenoxazine and dimeric carbazole. This can also provide some implications for the future in-depth study of small molecule electrochromism and the solution to the problem of difficult processing of small molecules.

This paper reports on an experimental research of a 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) enveloped 10-methylphenothiazine (MPT) catalyst (MPT-HP-β-CD) with high sensitivity and wonderful electrical conductivity for the electrochemical detection of reduced glutathione (GSH) in a neutral environment. We obtained a linear response range from 10−6 mol L−1 to 5.8 × 10−4 mol L−1 for GSH with a low detection limit of 2.87 × 10−7 mol L−1, providing a potentially usefulness in the development of sensors for non-enzyme detection of GSH.

Diffusivity of redox shuttle additive in solvent plays an important role in the design of Li-ion battery. As redox shuttle additive, 10-methylphenothiazine (MPT) can give good overcharge protection in LiFePO4-based Li-ion cells, therefore diffusion coefficient of MPT in solvent needs to be known. A different data processing method based on optical digital interferometry is put forward to determine diffusion coefficient in this work. This method is verified by KCl aqueous solution and the relative standard uncertainty of diffusion coefficient is about 2.3%. The diffusion coefficients of MPT in dimethyl carbonate (DMC) from 288.15 K to 313.15 K at several concentrations are measured and the corresponding calculation equation of diffusion coefficient is presented.

In this study, a novel dual-template molecularly imprinted polymer capable of simultaneously recognizing 4 phenothiazines and 5 benzodiazepines was synthesized. From the comparison of the 3D conformations of the two templates and the analytes, it was concluded that the shapes and sizes of the templates used in this study influenced the polymer's recognition ability. The polymer was used to prepare a solid phase extraction cartridge, which was used to purify the extract of the swine complete formula feed sample obtained with 10 mL acetonitrile/0.1% formic acid (3 : 7, v/v). The results were determined using ultra performance liquid chromatography. During the experiments, the flow rate, loading solvent, washing solvent and eluting solvent were optimized. The limits of detection for the 9 drugs were in the range of 1.5–10 ng g−1, and the recoveries from the fortified blank feed samples were in the range of 85.6–97.9%. This is the first study reporting the use of a molecularly imprinted polymer-based extraction method for determining the two classes of sedatives in animal feed.

Well-defined amphiphilic diblock copolymer poly (methyl methacrylate)-b-poly (N-isopropylacrylamide) grafted hollow spheres (HS-g-PMMA-b-PNIPAM) hybrid materials were synthesized via metal-free surface-initiated atom transfer radical polymerization (SI-ATRP). The ATRP initiators α-Bromoisobutyryl bromide (BIBB) were attached onto hollow sphere surfaces through esterification of acyl bromide groups and hydroxyl groups. The synthetic ATRP initiators (HS-Br) were further used for the metal-free SI-ATRP of methyl methacrylate (MMA) and N-isopropyl acrylamide (NIPAM) using 10-phenylphenothiazine (PTH) as the photocatalyst. The molecular weight of the polymers, structure, morphology, and thermal stability of the hybrid materials were characterized via gel permeation chromatography (GPC), X-ray photoelectron spectroscopy (XPS),1H-nuclear magnetic resonance spectroscopy (1H NMR), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), and thermogravimetric analysis (TGA), respectively. The results indicated that the ATRP initiator had been immobilized onto HS surfaces successfully followed by metal-free SI-ATRP of MMA and NIPAM, the Br atom had located at the end of the main PMMA polymer chain, and the polymerization process possessed the characteristic of controlled/“living” polymerization. The thermal stability of the hybrid materials was increased significantly compared to the pure PMMA and PNIPAM.Keywords:hollow spheres;metal-free ATRP;SI-ATRP;10-phenylphenothiazine (PTH);thermal stability

Aggregation-induced emission (AIE) materials can emit fluorescence with higher photoluminescence efficiency when aggregated or in the solid state, making them widely used in many fields recently. In this study, several novel N-substituted phenothiazine (PhT) derivatives HPMAD (HPMAC, HPMAN, HPMAP) with D-A structure were prepared by chemoenzymatic transesterification , Vilsmeier-Haack reaction and Knoevenagel condensation reaction , etc. Subsequently, the effects of functional groups with different natures on the optical properties of fluorescent molecules were investigated in detail. As compared with FPMA with an emission wavelength at 543 nm, the emission wavelengths of HPMAC, HPMAN and HPMAP were significantly red-shifted with the increase of electron-withdrawing and conjugation degree, and their maximum emission wavelengths were respectively at 595 nm, 599 nm and 649 nm. The quantum calculations also indicated that energy band gaps ΔE of HPMAC, HPMAN and HPMAP were obviously lower than that of the substrate FPMA, among which HPMAP had low ΔE of 3.04 eV due to the conjugation structure. Afterwards, amphiphilic copolymers PEG-HCC1, PEG-HCC2 and PEG-HCN were prepared by RAFT polymerization using PEGMA , HPMAC and HPMAN as monomers with different molar ratios, and their molar ratios in the copolymers were respectively about 23.7 %, 31.4 % and 30.8 %. Among them, PEG-HCN copolymers were easily dispersed in H 2 O solutions through self-assembly with a diameter of 100–200 nm, and exhibit significant aggregation-induced emission enhancement (AEE) phenomenon. Moreover, PEG-HCN FONs had excellent biocompatibility , lower toxicity, and good cellular endocytosis, which can be further used as a carrier for the anticancer drug of paclitaxel (PTX). Thus, drugs-carrying nanoparticles HCN-PTX FONs were constructed for drugs release and simultaneous imaging to track intracellular drug delivery , which demonstrates the potential for development in bioimaging, drugs delivery and medical diagnostics.

The residues of phenothiazines and benzodiazepines in foods of animal origin are dangerous to consumers. For inspection of their abuses, this study for the first time reported on the use of a chemiluminescence array sensor for the simultaneous determination of four phenothiazines and five benzodiazepines in pig urine. Two molecularly imprinted polymers were coated in different wells of a conventional 96-well microtiter plate as the recognition reagents. After sample loading, the absorbed analytes were initiated directly by using an imidazole enhanced bis(2,4,6-trichlorophenyl)oxalate–hydrogen peroxide system to emit light. The assay process consisted of only one sample-loading step prior to data acquisition, so one test was finished within 10 min. The limits of detection for the nine drugs in the pig urine were in a range of 0.1 to 0.6 pg/mL, and the recoveries from the fortified blank urine samples were in a range of 80.3 to 95%. Furthermore, the sensor could be reused six times. Therefore, this sensor could be used as a simple, rapid, sensitive and reusable tool for routine screening for residues of phenothiazines and benzodiazepines in pig urine.

Mitochondria are essential organelles in eukaryotic cells and act as the energy powerhouse and biosynthetic compartment. Fluorescent dyes are widely used powerful molecular tools for analytical sensing and optical imaging. Low photostability, short excitation and emission wavelengths , and aggregation-induced quenching effects restrict the application of traditional commercial mitochondrial fluorescent probes for bioimaging. In this study, using rhodamine as the acceptor and phenothiazine as the donor, we synthesized a novel mitochondrial-targeted near infrared (NIR) fluorescent probe, MIT-PZR. Due to low cytotoxicity, great photostability and high specificity for mitochondria targeting, MIT-PZR has enormous potential for cell imaging. Furthermore, with a sizeable Stokes shift (emission peak at 705 nm), MIT-PZR penetrated tissues providing stable red fluorescence for imaging in vivo . The histological assessment of various tissues after treatment with MIT-PZR indicated that it has good biocompatibility. Thus, MIT-PZR is a promising mitochondrial NIR fluorescent probe for future application in clinical diagnosis and modern biological research.
