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.
