Abstract: 9 Anthracenemethanol was anchored on silica gel using malonic acid as linker.The photoisomerization of trans-vitamin D3 to cis-vitamin D3 was carried out with this heterogeneous photosensitizer in ethanol and toluene solutions.The experiment results demonstrate that this solid photosensitizer is efficient for the photoisomerization and easy for separated from the reaction mixtures.

Key words: photoisomerization, solid phase sensitizer, vitamin D3
