【摘要】 <正> 1964年,Gilman 等人在研究芳基多硅烷的紫外光谱时,认为苯基五甲基二硅烷在231 nm 处的强吸收峰（ε10,900）是由于硅-硅键与苯环共轭,从而使苯的¹La 带红移的结果。尔后,Sakurai 等对此又进行了系统的研究,并提出了分子内电荷转移的机制(σ_?→π^*跃迁)。为了进一步了解硅-硅键与π-体更多还原

【Abstract】 Four series of α,ω-diaryl substituted permethylpolysilane were synthesized by thereaction of α,ω-dichloro permethylpolysilane and the corresponding aryl Grignard reagent.The relationship between their m.p.,UV and NMR with their molecular structures wasdiscussed.更多还原
