| 摘 要： | 本文研究了一系列芘甲酰基标记的苯乙烯—二乙烯苯共聚物的荧光光谱，发现其光谱特征对共聚物中芘甲酰基的含量，溶胀作用以及溶胀溶剂的性质有明显的依赖性．这一结果可以用芘甲酰基在共聚凝胶中形成激基缔合物和激基复合物予以解释．

| Abstract: | Studies have been made on the fluorescence spectra of a series ofstyrene/divinylbenzene copolymers containing pyrenoyl groups. It was found that thespectra of the copolymers depended on the solvation, concentration of pyrenoyl groups.The result can be explained in terms of the formation of excimer and exciplex in the polymer gels. |
