Synthesis and photophysical properties of poly(aryleneethynylene)s containing dibenzosilole unit

导出

摘要 A series of poly（aryleneethynylene）s containing dibenzosilole unit has been synthesized by palladium-catalyzed Sonogashira cross-coupling reactions with 2,7-diethynyl-9,9-dihexyl-3,6-dimethoxy-9H-dibenzosilole （4） as the key monomer. Their photophysical properties in solution were investigated. All of the polymers showed intense fluorescence with high quantum efficiencies.
