摘要

The title heteroarene (TBD) isoelectronic with perylene was synthesized by way of a dimerization of thieno [2, 3-b] thiophene. In addition, 1, 4, 5, 8-tetramethyl, tetraethyl, tetrakis (methylthio), and tetrakis (ethylthio) derivatives were readily obtained from TBD. An X-ray crystallographic analysis of TBD demonstrated that the molecular structure is quite planar and symmetrical, but strained in the bond angles. The crystal structure comprises ...
