摘要: 对α,ω-双香豆素长链化合物光二聚反应中盐效应、溶剂效应、粘度效应及连接体的长度和柔顺性等因素的影响进行了研究。借助1HNMR谱、UV吸收谱、荧光光谱分别对α,ω-双香豆素长链化合物在不同条件下的构象进行了分析,并解释了不同条件下的光二聚行为.

关键词: 盐效应, 溶剂效应, 粘度效应, 柔顺性, 光二聚

Abstract: The effects of salt,solvent, viscosity and the effects of length, flexibility of spacer between chromophores on the photodimerization reaction of α,ω-biscoumarin long chain polyether compounds have been studied in this work.With the aids of UVabsorption,fluorescence and 1H NMRspectra,the conformation of the title compounds under different conditions was analyzed. Based on the results obtained,the behavior of photodimerization of these compounds in different cases was discussed and explained.

Key words: Salt effect, Solvent effect, Viscosity effect, Photodimrization
