摘要：
The binding of bis-nitrogen ligands, 4,4'-bipyridine and pyrazine, to Zn(OEP), where OEP is octaethylporphyrin, has been characterized by electronic spectroscopy. The solvent effect and temperature on the binding constants have been studied. Also, based on variable temperature experiment, thermodynamic data for ligand binding to porphyrin have been reported. It is estimated that interaction between porphyrin and 4,4'-bipyridine and pyrazine is exothermic and has energy of -45 +/- 1.5 kJ mol(-1) and -31 +/- 1.7 kJ mol(-1), respectively.
