| Abstract: | Dichlorosilane monomer methyl-β-cyanoethyldichlorosilane, was prepared from acrylonitrile and methyl dichlorosilane in the catalytic system of N,N,N′,N′-tetramethylethylen-diamin (TMEDA)/Cu2O by hydrosilylation reaction. Consequently, a copolysilane poly(methyl-β-cyanoethylsilylene)-methylphenylsilylene was synthesized by Wurtz-type reductive coupling reaction of methyl-β-cyanoethyldichlorosilane and methylphenyldichlorosilane using sodium as catalyst in toluene. Furthermore, UV absorption, fluorescent and thermal properties of the copolysilane were investigated. Results reveal that the copolysilane bearing β-cyanoethyl side group possesses good thermal oxidative stability and strong fluorescence emitting at 412 nm. |
