| Abstract: | Copper tetra-4-(n-alkoxycarbonyl)phthalocyanines were synthesized, and their thermotropic and lyotropic mesomorphism at different lengths of lateral substituents was studied. Their possibility of forming both thermotropic and lyophilic mesophases (amphotropy) was found. The length of lateral substituents affects the type of supramolecular packing in the mesophase rather than the temperature of the crystal→mesophase phase transition. A rarecase of the mesogeneity of disk-like compounds of the same chemical nature possessing only four substituents is discussed. Translated fromIzvestiya Akademii Nauk.
