Summary: This study reports the electrodeposition of regioregular poly-3 ',4 '-didodecyl-2,2 ':5 ',2 ''-terthiophene onto a double-band electrode for in situ measurement of electrical conductance. The electrical conductivity of poly-3 ' 4 '-DDTT depended nonlinearly on the scan rate of electrodeposition and varied in the range 12 - 34 S cm(-1). The conductivity of poly-3 ' 4 '-DDTT was found to be closely related to the scan rate, oxidative coupling rate, and precipitation rate during electrodeposition.

Summary: This study reports the synthesis and characterization of PEGMA-based copolymers incorporating different percentages of HEMA-UPy and evaluates their thermal properties and healing efficiency. The results show that increasing the amount of HEMA-UPy moiety leads to slight changes in glass transition temperature and significant changes in crystallization and melting temperatures. Dynamic mechanical analysis demonstrates the ability of the copolymer to recover its original storage modulus values.

Summary: In the field of supramolecules, the fabrication of polyrotaxanes or poly-pseudo-rotaxanes remains a challenge. This study reports the formation of a poly-pseudo-rotaxane in which a single salt-type guest acts as both a linking and a threading agent. The use of A1/A2-thiopyridyl pillar[5]arene (L) and silver(I) trifluoroacetate in CHCl3/CH3OH produced a one-dimensional (1D) poly-pseudo-rotaxane. Surprisingly, the AgCF3CO2 guest not only linked the di-armed L ligands but also threaded into the pillar[5]arene cavity. However, a simple 1D coordination polymer was obtained in a different solvent due to the presence of a CH2Cl2 molecule in the pillar[5]arene cavity.

Summary: In recent decades, there has been a growing interest in preparing polymers with host or guest moieties, leading to the development of new materials with unique properties. This study demonstrates the potential for developing polymers with various combinations of polymer chains by polymerizing host-appended molecules with different monomers. The research also shows that long polymer chains do not hinder host-guest complexation, even when a fullerene derivative is equipped with a polymer chain.

Summary: A novel pillar[5]arene-based 3D polymer network was developed for efficient iodine removal from water, showing fast and simple preparation method and no structural change after iodine capture, with the ability of being reused multiple times. This polymer network can efficiently adsorb iodine due to non-covalent interactions and hydrophobic nature of pillararene, making it a promising material for environmental remediation.

Summary: This study synthesized five D-pi-A-pi-D compounds with different electron acceptors (TD, BTD, DPP, TZ, and NDI). By adjusting the solvent polarity, DTP-TD emitted yellow light, while DTP-BTD and DTP-DPP emitted near-infrared light. The electron affinities strongly depended on the nature of the acceptor, while the ionization potentials varied weakly. The experimental findings were supported by theoretical calculations and electrochromic behavior was observed in the polymers.

Summary: This research explores CO2 valorization through hydrogenation using non-noble metals (Ni and Cu) supported on graphitic carbon nitride (g-C3N4). The catalysts exhibit stable activity and good conversions. Increasing the operating temperature during CO2 hydrogenation leads to higher CO2 conversion and selectivity for CO, while decreasing selectivity for methanol. The study also highlights the potential of g-C3N4 as a support material for atom-economy-designed catalysts.

Summary: Six acridone derivatives containing either carbazole or phenoxazine substituents were synthesized to investigate the effect of linking patterns on their photophysical and electrochemical properties. These compounds exhibited reversible electrochemical oxidation and excellent luminescent properties. Compounds with carbazole substituents showed prompt fluorescence and aggregation-caused quenching, while compounds with phenoxazine substituents demonstrated thermally activated delayed fluorescence and aggregation-induced emission enhancement. The combination of redox, transport and luminescent properties makes these compounds suitable for optoelectronic applications.

Summary: By introducing two consecutive injections of sulfur and silver precursors, ternary and alloyed quaternary nanocrystals were successfully prepared, showing clearly separated photoluminescence peaks in both types of nanocrystals to confirm their heterogenic nature. The photoluminescence mechanism in the nanocrystals exhibited a simple exciton radiative recombination mechanism for the emission at shorter wavelengths with a nanosecond lifetime, while a more complex exciton trap state mechanism was observed for the emission at longer wavelengths with a microsecond lifetime depending on the composition of the ternary (or quaternary) phase.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
