4H-dithieno[3,2-b:2',3'-d]pyrrole has recently become a useful building block in the synthesis of donor-acceptor molecules with practical application in various organic technologies. The DTP molecule itself consists of a pyrrole ring with two fused thiophenes providing an alternative for the related dithieno[3,2-b:2′,3′-d]thiophene. Most notably, the significance of DTP-based low- and high-molecular weight species has increased in recent years since, upon proper processing, they allow to improve the performance of many fields of organic electronics. This review is a trial of a brief report on recent advances in modern DTP chemistry with examples of their applications, mostly in the area of organic photovoltaics. The scope of this manuscript was to present the structure-property relationships that had been found together with the development of DTP-based materials.

4H-二硫代[3,2-b：2'，3'-d]吡咯最近已成为合成供体-受体分子并在各种有机技术中得到实际应用的有用组成部分。DTP分子本身由带有两个稠合噻吩的吡咯环组成，为相关的二噻吩并[3,2-b：2'，3'-d]噻吩提供了另一种选择。最值得注意的是，近年来，基于DTP的低分子量和高分子量物质的重要性有所提高，因为经过适当的加工，它们可以改善许多有机电子领域的性能。这篇评论是对有关现代DTP化学的最新进展的简短报告的尝试，并简要介绍了其应用示例，这些应用主要用于有机光伏领域。
