  扩展的四硫富瓦烯的核心碳环聚合物：氧化还原控制的可逆转化为碳-苯甲酸酯阳离子。

  摘要：

  碳苯是通过在苯分子的每个C-C键内插入C 2个单元而设计的芳族分子。通过将相应的碳-喹啉核作为桥联单元整合在π-延伸的四硫富瓦烯（exTTF）中，表明可以通过电化学还原或氧化反应可逆地形成碳-苯环。所谓的碳水化合物因此，通过高度可见的热解石墨（HOPG）表面的UV-可见吸收光谱法和循环伏安法，X射线晶体学和扫描隧道显微镜（STM）来实验制备和研究了-exTTF分子。对该分子及其氧化和还原形式进行了密度泛函理论（DFT）级别的计算研究，以支持碳芳香性作为形成阳离子，自由基阳离子和自由基阴离子的驱动力。通过允许二硫代亚芳基环和碳-喹啉核共平面，碳-exTTFs展示了一种有前途的新型氧化还原活性系统。
