Abstract The data on the molecular design of porphyrin and phthalocyanine derivatives are presented. Construction of molecular models and their optimization using the HyperChem program were performed by MM+ method and the method of molecular dynamics. The prog-nosis of mesomorphism characteristic for discotic mesogens was implemented. As predicted by both methods, octacarboxypyrazinoporphyrazine (1), -pyridinoporphyrazine (2) and octa-carboxyphthalocyanine (3) should not possess mesomorphism, whereas 5-(4'-carboxyphenyl)-10,15,20-tris(4'-hexadecyloxyphenyl)porphin (4) is inclined to form columnar mesophases. The data obtained by two different methods are in good agreement with each other and corre-lated with the experimental results.
