2,7-Disubstituted dibenzosilole monomers have been prepared by the selective trans-lithiation of 4,4'-dibromo-2,2'-diiodobiphenyl followed by silylation with dichlorodihexylsilane. Suzuki copolymerization of dibromo and bis(boronate) monomers afforded poly(9,9-dihexyl-2,7-dibenzosilole) which showed better efficiency than the corresponding polyfluorene in a single layer light emitting device. Preliminary studies demonstrated this to be a promising blue light emitting polymer.
通过对4,4'-二溴-2,2'-二碘联苯进行选择性转锂化，然后用二氯二己基硅烷进行硅烷化反应，制备了2,7-二取代二苯并硅杂环戊二烯单体。二溴单体和双（硼酸酯）单体的铃木共聚反应得到了聚（9,9-二己基-2,7-二苯并硅杂环戊二烯），在单层发光器件中，该聚合物表现出比相应的聚芴更高的效率。初步研究表明，这是一种很有前景的蓝色发光聚合物。
