  In this article, a series of porphyrin-nicacid dyads and their Mn and Zn complexes were synthesized and characterized by elemental analysis, UV-Vis, IR, MS, and 1H NMR spectroscopies. Fluorescence studies show that for increasing length of alkoxy chains the fluorescence intensity and quantum yield of the porphyrin ligands is C2 > C3 > C4 > C5 > C6 > C10. Electrochemical results indicate that the length of side chain has little effect on the redox potential.

  The porphyrin nicotinic acid binary compounds with different substituents in porphine rings (5-(4-nicotinicoxyldecyloxy)phenyl-10,15,20-triphenylporhyrin 2a, 5-(4-nicotinicoxyldecyloxy)phenyl-10,15,20-tri(4-chlorophenyl)porphyrin 2b and 5-(4-nicotinicoxyldecyloxy)phenyl-10,15,20-tri(4-methoxyphenyl)porphyrin 2c) were synthesized. All of them have been characterized, assigned and analyzed by UV–vis, IR, MS and 1H NMR spectra. Their electrochemical and spectroscopic properties were studied by using cyclic voltammetry, fluorescence spectra and Resonance Raman spectra. Different substituents have a little influence on electrochemical behavior and fluorescence spectra. In the Resonance Raman spectra, the substituent has little influence on the skeleton vibration of porphyrin and has much influence on the vibration of phenyl.
