Abstract:
Chromium(III) porphyrin and its derivative have been synthesized by bromination and demetallation of copper tetra phenyl porphyrin.All the complexes were characterized on the basis of their elemental analysis, UV-vis spectra and magnetic moment properties.The magnetic moment suggested that the complex in the range 3.79 BM indicating an octahedral structure. The comparison of the UV- vis spectra of the free base show that substitution of Br atom at β-pyrrole position lead to greater shift than substitution of electronegative group in the phenyl ring.
