Abstract

A series of benzophenone (BP) and norbornadiene (NBD) labeled poly(aryl ether) dendrimers (G_n-NBD), generations 1～4, were synthesized. The intramolecular photosensitization was studied. Irradiation with ＞350 nm of a solution of G_n-NBD in degassed CH₂Cl₂ at room temperature resulted in a valence isomerization of the norbornadiene group to the quadricyclane group (G_n-QC). The observed rates of the isomerization became higher with the generation increase.

Key words: poly(aryl ether) dendrimer, norbornadiene, intramolecular photosensitization, benzophenone
