摘要/Abstract

摘要： 设计合成了1-3代芳醚骨架树枝形聚合物修饰的双8-羟基喹啉衍生物.对这些化合物在不同溶剂中的荧光光谱研究表明,随着代数的增加,目标树枝形聚合物的荧光量子产率增大,树枝形聚合物对核心发色团具有一定的隔离作用,并且目标分子内可以发生从骨架向核心发色团的能量传递.

关键词: 8-羟基喹啉, 树枝形聚合物, 能量传递

Abstract: A series of poly (aryl ether) dendrimers with bis-(8-hydroxyquinoline) attached to the core, generation 1-3, were synthesized. The steady state photophysical properties of these compounds in various solvents were studied. The results indicated that the fluorescent quantum yield increased with the generation increases. The dendritic structure showed isolating effect on the core. The intramolecular energy transfer from the dendritic structure to the core was observed.

Key words: poly (aryl ether) dendrimers, bis-(8-hydroxyquinoline), energy transfer
