Thermogravimetry of π–π complexes of zinc(II)tetra-tert-butylphthalocyanine with aromatic molecules

Physical-chemical characteristics of molecular complexes of Zn(II)tetra-tert-butylphthalocyanine (Zn(tert-Bu)4Pc) with aromatic solvents were obtained. The results show that polarization parameters of the interacting molecules play an important role in stabilization of the phthalocyanine π–π complexes. Dispersion forces are the major factor governing the π–π complex formation of Zn(tert-Bu)4Pc with aromatic molecules. The metallophthalocyanine may be applicable as efficient analytical reagent for separation of isomeric forms of aromatic molecules.
