摘要：

The absorption spectra of radical ions of polysilastyrene have been measured in rigid matrices at 77 K as well as in solution at room temperature by using gamma -irradiation and pulse radiolysis methods. The radical anion with lambda //m//a//x at 365 nm was observed in irradiated 2-methyltetrahydrofuran, while the radical cation with two absorption bands at 358 and 2000 nm was observed in irradiated n-butyl chloride at 77 K. Upon thermal annealing, the infrared band showed a blue shift to 1700 nm, which is attributed to the geometrical reorientation of pendant phenyl groups from the unrelaxed to relaxed dimer radical cation conformation.
