Summary: The novel core-substituted naphthalene diimide derivative, DPyNDI-TPA, showed distinct morphology and ionization capability due to the introduction of pyrrolidine groups. The wrapped counter anions in DPyNDI-TPA polymer films acted as balancing charges in electrochromic processes, resulting in improved electrochromic performance. This meaningful design provides new concepts for organic electrochromic materials and has great prospects in optoelectrical materials.

Summary: This study compares the structural and electrochemical properties of newly synthesized N-substituted carbazole monomers with different aniline derivatives using a combination of experimental and computational methods. The substitution of fluorine atoms leads to an anodic shift in the oxidation potential, and the poly(E)-N-(4-(9H-carbazol-9-yl) benzylidene) aniline (PACA) polymer film exhibits better optical contrast, response time, and electrochemical stability.

Summary: This study achieved controlled NNTA polymerization in amide polar solvents by adding acetic acid as a promoter, producing polypeptoids with designable molecular weights and low dispersities. The presence of acetic acid not only accelerated polymerization, but also suppressed H2S-catalyzed decomposition, leading to preparation of high molecular weight polysarcosines.

Summary: This study demonstrates the modification of polyolefin separator using a nitrogen-rich conjugated microporous polymer (NCMP) for improved lithium-sulfur (Li-S) batteries. The in situ polymerization process generates a thin NCMP coating with abundant nitrogen-containing groups, uniform nanopores, and pi-conjugated structure. This coating effectively suppresses Li polysulfide shuttle and regulates the nucleation and growth of Li dendrites. As a result, the NCMP-based separator significantly enhances the cycling stability of the Li-S battery under high sulfur loading, lean electrolyte, and limited lithium excess conditions.
