摘要：
Two kinds of polymer-bound photosensitizers were synthesized, in which anthracene acts as sensitizer moiety, polystyrene (PS) and poly(methyl methylacrylate) (PMMA) serve as solid phase supports, respectively. The photoisomerization of tachysterol to previtamin D-3 was carried out with these polymer-bound photosensitizers in ethanol and toluene solutions. The experiment results demonstrate that these solid phase photosensitizers are efficient for the photoisomerization with good recycle property and can be simply separated from the reaction mixtures by filtration.
