通过重复氧化偶联完全被β封闭的异硫杂环己烯，开发了一系列长达96聚体的超长低聚硫吩类化合物。它们是高度共轭的，类似于未取代的低聚硫吩类化合物，并且该体系的有效共轭扩展到96个噻吩基，比先前推测的聚噻吩类化合物的有效共轭长度要长得多。
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.
