【Abstract】 The spectral properties of five kinds of synthesized porphyrins were. Studied. It was found that the fluorescence intensity enhanced with the increase in number of peripheral hydroxyl group of porphyrin, and that the fluorescence intensities of tetrahydroxyphenyl porphyrin and tetraphenyl porphyrin at 430 nm were very low, which was related to the structure symmetry. The red-shift of the fluorescence spectra in DMF compared to that in CH 2Cl 2 can be explained on the bases of the effect of solvation. These results indicate that the compounds with different fluorescence properties could be obtained by controlling the number and the position of peripheral substitute groups of porphyrin and using different solvents.更多还原
