摘要：

Eight kinds of organopolysilane radical anions in tetrahydrofuran solution were investigated utilizing the pulse radiolysis technique. UV absorption maxima of poly(alkylsilane) radical anions are observed at 355-363 nm. Introducing a methylphenylsilylene unit or diphenylsilylene unit into the polymer chains causes a slight red shift in the UV absorption of their radical anions. This can be understood on the basis of an electronic interaction between the silicon main chain and pendant phenyl groups. Extinction coefficients of these radical anions were determined to be 1. 4-2. 1 multiplied by 10**5 per mol of added electron.
