2,3,9,10,16,17,23,24-Octakis-[(4-phenoxy)phenoxy]phthalocyanine and Its Erbium Complexes. Synthesis, Spectral, and Luminescent Properties, Self-Association

Abstract

4,5-bis[(4-phenoxy)phenoxy]phthalonitrile was obtained by the reaction of 4,5-dichlorophthalonitrile with 4-phenoxyphenol. On its basis 2,3,9,10,16,17,23,24-octakis-[(4-phenoxy)phenoxy]phthalocyanine and its single- and double-decked complexes with erbium were synthesized. Spectral-luminescent properties of resulting phthalocyanines were studied. The tendency of phthalocyanines to association in dichloromethane depends on the structure of their molecules.
