通过使用脉冲激光激发，研究了聚苯乙烯和一系列苯乙烯-甲基丙烯酸甲酯共聚物的时间分辨荧光行为。尽管含苯乙烯和含萘聚合物的光物理特性可以通过相同的一般动力学方案来描述，但光物理相互作用的性质上的一些差异是明显的。提出了在掺有苯乙烯发色团的聚合物中准分子解离成激发态单体的明确证据。
The time-resolved fluorescence behavior of polystyrene and a series of styrene–methyl methacrylate copolymers has been examined by using pulsed laser excitation. Although the photophysical characteristics of styrene- and naphthalene-containing polymers may be described by the same general kinetic scheme, some differences in the nature of the photophysical interactions are apparent. Umambiguous evidence for the occurrence of excimer dissociation into excited-state monomer in polymers incorporating styrene chromophores is presented.
