本文研究了聚甲基苯乙基硅烷(PMPES)的荧光光谱。从浓度效应和猝灭规律证明了PMPES溶液中既有分子间激基缔合物又有分子内的激基缔合物。低温荧光光谱说明在基态时有部分生色团呈激基缔合物构象。
In this paper, the fluorescence spectra of polymethylphenylsilane (PMPES) were studied. From the effect of concentration and quenching, we proved that there are both exciplex and intramolecular exciplex in PMPES solution. Low-temperature fluorescence spectra indicate that some chromophores are excited at the ground state as an excimer.
