文摘
Three generations of bithiophenesilane monodendrons and dendrimers consisting of 3−45 2,2′-bithiene-5,5′-diyl units were synthesized by means of effective coupling reactions between the corresponding bithienyllithium derivatives and chlorosilanes. These compounds show efficient photoluminescence in the violet-blue region, the quantum yield of which is 5−15 times higher than that for the parent bithiophene or bithiophenesilanes.
