Synthesis, structural investigations and biological studies on symmetrically substituted 4,4′,4″,4″′- tetra-methoxyphenylimino phthalocyanine complexes

The synthesis and characterization of novel metal(II) 4,4′,4″,4″′-tetra-methoxyphenylimino substituted phthalocyanines (MImPc) of copper(II), cobalt(II), nickel(II) and zinc(II) by condensing the 4,4′,4″,4″′-tetra amino phthalocyanines with anisaldehyde are described. The dark bluish green colored tetraimino substituted phthalocyanine derivatives are characterized by various physico-chemical techniques, elemental analysis, magnetic susceptibility, electronic, and IR spectra, powder X-ray diffraction and thermo gravimetric analysis (TGA) to check the structural integrity and purity. The variations of magnetic moment as a function of field strength indicated the presence of intermolecular co-operative interactions. The complexes are also evaluated for their antifungal and antibacterial activities.
