Abstract

Copper (II) and nickel (II) complexes of 2,3,9,10,16,17,23,24-octa(dodecyloxy)phthalocyanine (1a, 1b) and copper (II) complex of 2,9,16,23-tetra(decy1thio)phthalocyanine (1c) have been synthesized and their liquid crystalline properties have been studied. It was established, that 1a-c possess both thermotropic and lyotropic (with apolar organic solvents) mesomorphism. Lyomesomorphism exhibited by compounds can be attributed to chromonic type.
