摘要: 有关α,ω-双香豆素长链化合物的分子内光二聚反应,在不同极性溶剂中均发生反应的事实,使人们考虑到有可能在非极性溶剂中使带有阻碍基团的4-甲基豆素也易发生光二聚反应。为此我们以三缩四乙二醇为支撑体合成了α,ω-双(4-甲基香豆素)长链化合物,并研究了它的光二聚反应。

Abstract: The title compound(Ⅰ)containing two coumarin chromophores linked by polyethyleneglycol was synthesized. Its photodimerization process was also studied. The 1HNMR data of compound(Ⅰ)and its dimer(Ⅱ)indicates that the syn head-to-tail dimer is the only regioisomer. The kinetics of dimerization of compound(Ⅰ) was reported.

Key words: photodimerization reaction, coumarin, photocycloaddition
