本工作对聚(乙烯基二苯甲酮)及其共聚物在玻璃态(77K)时的磷光光谱进行测定.发现在相同发色团浓度条件下,聚(乙烯基二苯甲酮)有着最低的磷光强度,说明聚(乙烯基二苯甲酮)体系存在着严重的T-T湮灭过程.用降冰片二烯去淬灭聚(乙烯基二苯甲酮)及其共聚物磷光时,所得结果能较好地符合Stern-Volmer关系式,表明其间存在着能量迁移的作用。
In this work, the phosphorescence spectra of poly (vinylbenzophenone) and its copolymers in the glassy state (77K) were measured and found to have the lowest poly (vinylbenzophenone) at the same chromophore concentration , Indicating that there is a serious TT annihilation process in poly (vinylbenzophenone) system.When norbornene is used to quench the phosphorescence of poly (vinylbenzophenone) and its copolymer, the results obtained It is in good agreement with the Stern-Volmer relation, indicating that there is an energy transfer between them.
