Poly(2,7-dibenzosilole): A Blue Light Emitting Polymer

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...

Zusammenfassung:	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.
