Summary: This study synthesized five arylene diimides with multi-electrochromic properties and investigated their electrochemical activity, solubility, and switching stability. The results showed that the introduction of tert-butyl substituents on the PTZ active sites reduced the oxidation potential, increased solubility, and significantly improved the electrochromic performance. Electrochromic devices using these compounds as electroactive materials were constructed and their performance was studied.

Summary: The naphtalenediimide-triphenylamine monomer (NDI-TPA) was synthesized and used to form a thin polymer layer on the electrode surface via electropolymerization. The monomer contains four triphenylamine groups and forms a cross-linked multielectrochromic polymer that changes color during oxidation and reduction. The influence of temperature on the electrochemical and electrochromic properties of the polymer coating was investigated, showing that higher temperatures result in faster and more reversible electrochemical reactions, shorter response times, but also faster degradation of the polymer film.

Summary: The introduction of water into the Li+-based electrolyte has been found to improve the pseudocapacitive characteristics and reaction kinetics of NiO electrodes. This enhancement is attributed to an increase in the number of ions and a reduction in electrolyte resistance and interfacial charge-transfer resistance, leading to better electrochemical and electrochromic properties. These results significantly contribute to the reversibility and stability of the active interfaces in high-performance electrochromic devices.

Summary: Two conducting macromolecules, P1 and P2, with adjustable color changes under an electric field were successfully fabricated on the ITO substrate via electrochemical polymerization for the first time. The P1 film exhibited yellowish-brown color in neutral and reduced states, and dark brown color in oxidized states, while the P2 film showed orange color in neutral states, brownish orange color in oxidized states, and dark brown color in reduced states. P1 showed higher conductivity, shorter switching time, and better stability, while P2 exhibited advanced chromic and electron-withdrawing characteristics attributed to the substituted phenyldiazenyl units and lower oxidation potential.

Summary: In this study, a novel type of D-A non-fused-ring copolymers was designed and synthesized to overcome the trade-off relationship between electrical conductivity and Seebeck coefficient in organic semiconductors. The incorporation of fluorine atoms into the polymer backbone effectively increased the ordered degree of molecular stacking and improved both the electrical conductivity and Seebeck coefficient. The bimodal orientation of polymers played a crucial role in decoupling the correlation between electrical conductivity and Seebeck coefficient.

Summary: This research focuses on the versatile substance, polyaniline/layered double hydroxide (PANI@Nd-Co/LDH), under solvothermal conditions. A thorough analysis of its structure and morphology was conducted using various analytical methods. The findings showed that PANI@Nd-Co/LDH exhibited highly sensitive and specific fluorescence detection of Pb(II) and Al(III), outperforming other heavy metal ions. The sensor demonstrated a turn-off fluorescence response for Pb(II) ions and a turn-on fluorescence response for Al(III) ions. The minimum detectable limits (MDL) were determined to be 9.6 nM for Pb(II) and 220 nM for Al(III). PANI@Nd-Co/LDH could be easily regenerated and reused for multiple cycles. The detection mechanisms involved the inner filter effect (IFE) for Pb(II) and the chelation-enhanced fluorescence (CHEF) effect for Al(III). These results highlight the excellent potential of PANI@Nd-Co/LDH in the detection and recognition of Pb(II) and Al(III) ions.
