二噻吩并噻吩的单连接和乙烯基连接二聚体表现出不同的电子行为。单连接的二聚体的单晶显示出0.265 S cm（-1）的高电导率，比乙烯基连接的二聚体高5个数量级。单连接二聚体的空穴密度的巨大增加是由于自由基的形成，自由基可以通过简单的热脱掺杂可逆地调节。
Singly linked and vinyl-linked dimers of dithienothiophenes exhibit different electronic behaviors. Single crystals of the singly linked dimer show a high conductivity of 0.265 S cm(-1) , five orders of magnitude higher than that of the vinyl-linked dimer. The huge increase in the hole density of singly linked dimers results from the formation of radicals, which can be reversibly tuned by facile thermal de-doping.
