Abstract The asymmetrical phthalocyanines of A3B, ABAB and AABB types were synthesized by the interaction of 3,6-dioctyloxypthalonitrilie (component A) and 3,4,5,6-thetra-chloropthalonitrile (component B). Their mesomorphic properties were investigated by polarization optical microscopy method. It was established that the compounds of A3B, ABAB and AABB types possessed thermotropic mesomorphism. They kept their mesophase texture at cooling. All these compounds formed lyomesophases in binary systems with toluol, chloroform, DMFA, DMSO. Copper complexes of asymmetrical phthalocyanines of ABAB and AABB types did not possess thermotropic mesomorphism.
Keywords: synthesis, asymmetrical phthalocyanines, lyotropic and thermotropic mesomorphism
