Synthesis, characterizations and biological studies of symmetrically substituted 2, 9, 16, 23-tetra-hydroxyphenylimino phthalocyanine complexes

The recent paper describes the synthesis and characterization of metal (II) 2, 9, 16, 23-tetra-hydroxyphenylimino phthalocyanines (M-OHPhImPc) of Co (II), Cu (II), Ni (II), and Zn (II). The dark bluish green colored tetramino substituted phthalocyanine derivatives are characterized by the various physico-chemical techniques such as elemental analysis, magnetic susceptibility, UV-Visible, IR, powder X-ray diffraction, and thermogravimetric analysis to check the structural integrity, purity, and thermal stability. The variations of magnetic moment as a function of field strength indicated the presence of intermolecular co-operative interactions. The above said compounds were screened for their antibacterial and antifungal activities.
