摘要: 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。

Abstract: In this paper the excimer fluorescence of poly[methy(β-phenethyl) silyene] (PMPES) was studied.By concentration quenching, adding precipitant and quenching medium, the fluorescence of monomer and excimer in PMPESsolution is proved.The excimers originate from the interaction of interchain or intrachain phenyl groups.Through studying the fluorescence spectrum of PMPESat 77K, partial chromophores were found to form excimer' s conformation at ground state.

Key words: Poly[methyl(β-phenethyl)silyiene], The fluorescence of excimet, Concentration effect, Fluorescence quenching
