摘要：

Bis-porphyrins with different substituents were synthesized via the linkage of (E)-2-butenedioyl dichloride and characterized by IR, UV-Vis, H-1 NMR and MS spectra. Also, their spectroscopic properties were studied by SPS, fluorescence spectra and Raman spectra. The results show that the substituents have great influences on the quantum yield of fluorescence, the methoxy groups increase the intensity and the quantum yield of the porphyin while the chloric groups decrease them. This suggests that electron-withdrawing groups (-Cl) have stronger influence on fluorescence property of porphyrin than electron-donating groups (-OCH3). The electronic effects of substituent group influence on the Raman spectra of porphyrin dimers are also great.
