New stable dibenzo[bc,fg][1,4]dithiapentalene (1) was prepared by heating 1,9-bis(methylthio)-dibenzothiophene in a glass tube. The X-ray analysis of 1 reveals clearly that it has a completely planar structure. Repeated scanning of cyclic voltammetry of 1 shows an analogous voltammogram with that of polythiophene.
通过在玻璃管中加热1,9-双(甲硫基)-二苯并噻吩制备新的稳定的二苯并[ bc,fg ] [1,4]二硫杂戊烯(1)。对1的X射线分析清楚地表明,它具有完全平面的结构。循环伏安法的重复扫描(1)显示出与聚噻吩类似的伏安图。
