Abstract

Abstract:

The thermodynamics of axial coordination reactions of Fe-phthalocyanine with various ligands of imidazoles in DMF solution has been studied. The axial coordination number(n)and equilibrium constants (βn) of the coordinating reaction were determined by spectral techniques. The steric and electrionic effects of the axial ligands were compared. The influence of temperature on the coordination reactions was discussed. The difference of axial coordinations of metallo-phthalocyanine and metallo-porphyrin with imidazoles was also analyzed.

Key words: Metallo-phthalocyanine, Imidazole, Thermodynamics, Axial coordiation
