Abstract

A series of extraordinarily long oligothiophenes up to the 96-mer has been developed by iterative oxidative coupling of the completely β-blocked sexithiophene. They are highly conjugated like nonsubstituted oligothiophenes, and the effective conjugation of this system is extended to 96 thiophene units and much longer than that previously speculated for polythiophenes.
