合成了一系列新型的三聚体、六聚体、二十二聚体和十二聚体等低聚硫杂环化合物，并在分子侧面连接了苄基醚树枝。由于树枝状悬挂物阻止了π-二聚体的形成，掺杂下的十二聚体的电子吸收光谱揭示了链二聚体和双极化子作为其他可能的导电聚噻吩载流子物种的参与。
A series of novel oligothiophenes, trimer, hexamer, nonamer, and dodecamer, attached with benzyl ether dendrons at the molecular sides has been developed. Since the dendron pendants prevent the formation of π-dimers, the electronic absorption spectra of the dodecamer under doping reveal the involvement of chain dimers and bipolarons as other possible charge carrier species for conductive polythiophenes.
