Since their discovery in the seventies, conducting polymers have been chemically designed to acquire specific optical and electrical properties for various applications. Poly(3,4‐ethylenedioxythiophene) (PEDOT) is among the most successful polymers as indicated by ≈12 000 articles mentioning it to date. PEDOT is found as transparent polymer electrodes in solar cells and light‐emitting diodes, as printed electrodes in transistors, and as the main component of electrochromic displays, supercapacitors, and electrochemical transistors. For around seven years, PEDOT has been classified as the first thermoelectric polymer that converts heat flow into electricity. This has triggered a renewed interest in the scientific community, with about 400 publications including the keyword “PEDOT” and “thermoelectric.” Among the topics covered by those scientific works are: i) the optimization of the thermoelectric properties, ii) understanding of the interplay between electrical properties and morphology, iii) the origin of the Seebeck coefficient, iv) the characterization of its thermal conductivity; and v) the design of thermoelectric devices. This work aims to be a pedagogical introduction to PEDOT but also to review the state‐of‐the art of its thermoelectric properties and thermoelectric devices. Hopefully, this work will inspire scientists to find chemical design rules to bring organic thermoelectrics beyond PEDOT.

聚（3,4-乙撑二氧噻吩）：化学合成，输运性质和热电器件

自从其在70年代被发现以来，导电聚合物就已经进行了化学设计，可以为各种应用获得特定的光学和电气特性。聚（3,4-乙撑二氧噻吩）（PEDOT）是最成功的聚合物之一，据迄今约有1200篇文章提到。PEDOT被用作太阳能电池和发光二极管中的透明聚合物电极，晶体管中的印刷电极，以及电致变色显示器，超级电容器和电化学晶体管的主要成分。大约七年来，PEDOT被列为第一种将热流转化为电能的热电聚合物。这引起了科学界的重新关注，包括关键字“ PEDOT”和“热电”的约400种出版物。”这些科学著作涵盖的主题包括：i）热电性能的优化，ii）理解电性能和形态之间的相互作用，iii）塞贝克系数的起源，iv）导热系数的表征；v）热电设备的设计。这项工作的目的是对PEDOT进行教学上的介绍，同时也要回顾其热电特性和热电设备的最新技术。希望这项工作将激发科学家寻找化学设计规则，将有机热电学带到PEDOT之外。v）热电设备的设计。这项工作的目的是对PEDOT进行教学上的介绍，同时也要回顾其热电特性和热电设备的最新技术。希望这项工作将激发科学家寻找化学设计规则，将有机热电学带到PEDOT之外。v）热电设备的设计。这项工作的目的是对PEDOT进行教学上的介绍，同时也要回顾其热电特性和热电设备的最新技术。希望这项工作将激发科学家寻找化学设计规则，将有机热电学带到PEDOT之外。
