摘要：

Novel sigma-pi conjugated polymers were prepared by alternating boration copolymerization between 1,2 diethynyl-1,1,2,2-tetramethyldisilane and aromatic diynes using diphenylbromoborane. The gel permeation chromatographic analysis (GPC) showed that the number average molecular weights (M-n) of the obtained polymers were several thousands. For example, M-n of the polymer produced from 2,7-diethynylfluorene was 5700 (yield 30%). The polymers were soluble in common organic solvents such as THF, chloroform and dichloromethane. The polymer having the fluorene unit was moderately fluorescent. The structures of the polymers were supported by H-1 NMR, B-11 NMR, Si-29 NMR, and IR spectra.
