Synthesis and properties of 2,3,9,10,16,17,23,24-octakis(3-phenoxyphenoxy)phthalocyanine and its complexes with erbium of diverse structures

Resumo

Reaction of 4,5-dichlorophthalonitrile with 3-phenoxyphenol led to the formation of 4,5-bis(3-phenoxyphenoxy)phthalonitrile. It has underlain the synthesis of 2,3,9,10,16,17,23,24-octakis(3-phenoxy-phenoxy) phthalocyanine and its single and double deck sandwich complexes with erbium. As show the electron absorption spectra the complexes are dissociated in dichloromethane at concentrations below 1 × 10^–5 mol L^–1.
