The photoisomerization of trans-vitamin D3 to cis-vitamin D3 was carried out with this polymer-bound photosensitizer in ethanol and toluene solutions. The experiment results demonstrate that this solid photosensitizer is efficient for the photoismerization and easy for separation from the reaction mixtures. 关 键 词：Polymer-bound SENSITIZER PHOTOISOMERIZATION trans-Vitamin D3 cis-Vitamin D3 维生素D3 光学异构化 感光剂
