The synthesis and electrochemical redox properties of a series of symmetrical, highly conjugated bis(benzo-1,3-dithiole) and bis(benzothiazole) derivatives (8)–(24) are described. The heterocyclic end-groups are linked by a conjugated framework that incorporates the following groups: (a) phenyl, (b) naphthyl, (c) thienyl, (d) biphenyl, (e) anthracenyl, and (f) benzanthracenyl. Compounds (13) and (16)–(19)
描述了一系列对称的,高度共轭的双(苯并-1,3-二硫醇)和双(苯并噻唑)衍生物(8)–(24)的合成和电化学氧化还原性能。杂环端基通过结合有以下基团的共轭框架连接:(a)苯基,(b)萘基,(c)噻吩基,(d)联苯,(e)蒽基和(f)苯并蒽基。化合物(13)和(16)–(19)在循环伏安图中显示两个单电子氧化还原波,而化合物(8)–(12),(14),(15),(20),(21) ,(23)和(24)显示单二电子氧化还原波。这些分子的氧化还原电势可以与其中中心桥环为芳族的系统的氧化还原态的增加的稳定性相关。
