Two-step synthesis of EDOT (3,4-ethylenedioxythiophene) derivate bearing a carboxylic acid group (carboxyl-EDOT) is presented. This reactive monomer has been copolymerized with EDOT to afford PEDOT copolymers. Thanks to the most common additives usually added to the PEDOT:PSS dispersion, ethylene glycol and 4-dodecylbenzenesulfonic acid (DBSA), the carboxylic acid has been used to cross-link the material via esterification reactions. This result offers the possibility to produce a polymer network without adding any cross-linking agent. Furthermore, the short synthetic pathway of carboxyl-EDOT offers the possibility to incorporate new functionality either in EDOT monomer or in PEDOT materials with a reasonable chemical effort and background.

合成羧基-EDOT 作为 PEDOT:PSS 的多功能添加剂和添加剂

介绍了带有羧酸基团 (羧基-EDOT) 的 EDOT (3,4-乙烯二氧噻吩) 衍生物的两步合成。这种反应性单体已与 EDOT 共聚以提供 PEDOT 共聚物。由于通常添加到 PEDOT:PSS 分散体中的最常见添加剂、乙二醇和 4-十二烷基苯磺酸 (DBSA)，羧酸已被用于通过酯化反应交联材料。该结果提供了在不添加任何交联剂的情况下生产聚合物网络的可能性。此外，羧基-EDOT 的短合成途径提供了在 EDOT 单体或 PEDOT 材料中加入新功能的可能性，并具有合理的化学努力和背景。
