摘要：

New sigma - pi conjugated alternating silylene-diacetylene copolymers, -[(SiMe2)m-C=C-C=C]n-, m=1, 3, 4, and 6, were synthesized by the reaction of alpha, omega-dichloropermethylated oligosilanes with dilithiobutadiyne, LiC=C-C= CLi. The IR spectra clearly indicated the presence of diyne unit in the polymer backbone. The influence of the chain length m of the dimethylsilylene unit in the -[(SiMe2)m-C=C-C=C]n- backbone on the optical and the electrical properties was investigated.
