The prognostication of columnar mesophases - Synthesis and mesomorphism ofsome porphyrin derivatives

The existence of columnar mesophases (CM) for a new series of the porphyrin derivatives is predicted. With this purpose, the computation of molecular parameters (K, K-c, K-s, K-p, M-m, M-r) is carried out for eighty five mole cules, including materials with a small number of peripheral substitutes. F or verification of the existence of CM in the series of materials examined, some of them are synthesized and their mesomorphism is investigated.
