摘要：

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. Copyright © 2005 American Chemical Society.
