dc.description.abstractVanadylphthalocyanine with four naphthoxy pendant groups on the periphery was prepared by cyclotetramerization of 4-(2-naphthoxy)phthalonitrile. The new compound was characterized by elemental analyses, Mass, IR and UV-Vis spectral data. The electronic spectra exhibit an intense absorption peak at 703 nm indicating the C-4v symmetry of VOPc. VO2+ ion in this structure was studied using electron paramagnetic resonance (EPR) technique at room temperature. The covalent bonding parameter for VO2+ ion and Fermi contact term were calculated using the principal axis values of the g and hyperfine splitting obtained from powder EPR spectrum.
