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
