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.
本文介绍了带有羧酸基团的3,4-亚乙基二氧噻吩（EDOT）衍生物（羧基-EDOT）的两步合成方法。该活性单体已与EDOT共聚以得到聚3,4-乙撑二氧噻吩（PEDOT）共聚物。借助通常添加到PEDOT：聚（3,4-乙撑二氧噻吩）-聚苯乙烯磺酸盐分散体中的最常见添加剂——乙二醇和4-十二烷基苯磺酸（DBSA），羧酸已通过酯化反应用于使材料交联。该结果提供了在不添加任何交联剂的情况下制备聚合物网络的可能性。此外，羧基-EDOT的短合成路线提供了以合理的化学工作量和背景在EDOT单体或PEDOT材料中引入新功能的可能性。
