Synthesis of Silafluorene on Dendritic Periphery

  • 발행 : 2007.11.20

초록

Carbosilane dendrimers with silafluorenyl groups on the periphery were prepared by the reaction of 2,2'- dilithiumbiphenyl and dichlorosilyl groups on the carbosilane dendrimers at low temperature. The 1st to 4th generation of dendrimers with silafluorenyl groups were obtained with high yields and the products were purified by column chromatography. The unified properties of the dendrimers were measured by gel permeation chromatography (GPC) and displayed very low and regular polydispersity index (PDI) value. The silafluorenyl moieties on dendritic periphery accepted the potassium fluoride ions which were stabilized by criptand [222], and it proved strong photoluminescent properties.
