A series of glycolated polythiophenes for use in organic electrochemical transistors (OECTs) is designed and synthesized, differing in the distribution of their ethylene glycol chains that are tethered to the conjugated backbone. While side chain redistribution does not have a significant impact on the optoelectronic properties of the polymers, this molecular engineering strategy strongly impacts the water uptake achieved in the polymers. By careful optimization of the water uptake in the polymer films, OECTs with unprecedented steady‐state performances in terms of [μC^*] and current retentions up to 98% over 700 electrochemical switching cycles are developed.

侧链再分布作为提高有机电化学晶体管性能和稳定性的策略。

设计并合成了一系列用于有机电化学晶体管（OECT）的乙醇化聚噻吩，它们的乙二醇链束缚在共轭骨架上的分布不同。尽管侧链的重新分布对聚合物的光电性能没有重大影响，但这种分子工程策略强烈影响了聚合物中实现的吸水率。通过仔细优化聚合物薄膜中的吸水率，开发出了以[ μC ^* ]表示的，具有前所未有的稳态性能且在700个电化学开关循环中电流保持率高达98％的OECT 。
