聚酰亚胺共轭导电聚合物的发现和发展对有机电子学领域产生了重大影响。由于这些聚合物具有在半导体和导电状态之间转换的能力，以及通过控制掺杂、化学修饰和与其他材料堆叠或创建复合材料来改变机械性能的能力，因此它们在未来的光学和电子设备中显示出巨大的集成潜力。在PI共轭聚合物中，聚噻吩酮及其衍生物是研究最广泛的聚合物之一，在发光二极管、净水装置、储氢和生物传感器等电子器件中的应用得到了广泛的计算和实验研究。从低聚噻吩型到无限链长(周期边界条件)的各种理论模拟研究已经被用来研究这些聚合物的各种电子和结构性质。在这篇综述中，我们从基本观点到器件应用，讨论了对原始聚噻吩类及其衍生物的理解的最新进展。
The field of organic electronics has been heavily impacted by the discovery and development of pi-conjugated conducting polymers. These polymers show great potential for integration into future optical and electronic devices due to their capacity to transition between semiconducting and conducting states as well as the ability to alter mechanical properties by controlled doping, chemical modification, and stacking or creating composites with other materials. Among pi-conjugated polymers, polythiophene and its derivatives has been one of the most extensively studied and is widely investigated computationally and experimentally for use in electronic devices such as light-emitting diodes, water purification devices, hydrogen storage, and biosensors. Various theoretical modeling studies of polythiophene ranging from an oligothiophene approach to infinite chain lengths (periodic boundary conditions) have been undertaken to study a variety of electronic and structural properties of these polymers. In this review, we discuss the recent advances in the understanding of pristine polythiophene and its derivatives from fundamental perspectives to device applications.
