  使用大取代基提高二噻吩并[3,2-b:2',3'-d]噻吩衍生物的氧化还原稳定性

  摘要：

  摘要 为了提高二噻吩并 [3,2-b:2',3'-d] 噻吩 (DTT) 的长期氧化还原稳定性，我们合成了具有不同大小取代基的衍生物。众所周知，DTT 2、6 位的取代基在这方面是有活性的。我们在本文中提供了对机制的更多见解。本研究为规模效应提供了第一个支持。DTT 2、6 位的大尺寸取代基比小尺寸取代基更有效。在这些化合物中，DTT 充当 HOMO 所在分子的核心，而取代基充当笼子以保护核心免受来自外部的各种攻击。这种核心笼系统不仅可以有效防止聚合，而且还可以提高长期氧化还原稳定性。具有大尺寸取代基的化合物，如 (1,1':3', 1″-三联苯)-2-基和4,4'-二-叔丁基-(1,1'-联苯)-2-基表现出优异的长期氧化还原稳定性。氧化电位在分别高达 17,000 次和 20,000 次的重复氧化过程中保持不变。具有小尺寸取代基的化合物，如苯基和甲基，显示出该耐久性的 1/10 或更少
