Abstract
The potential curve of molecules' pair interaction of smectic C liquid crystals: C5H11O-(OH)C6H3-CH = N-C6H4-C5H11 (A), C10 H21 O-C6H4-CH = CH-C6H4-OC10H21 (B) and ferroelectric smectic C* liquid crystals: C7H15O-C6H4-C6H4-COO-CH2C*H(CH3)C2H5 (C), C8H17O-C6H4-C6H4-C2H4C*H(CH3)C2H5 (D) and binary systems {A + C), {A + D) by atom-atom potential method is studied. It was shown that the intermolecular interaction considerably influences the conformation of isolated molecules. It was found that for CC, DD and AD interactions the most beneficial molecules’ packing in terms of energy is the antiparallel one (tl) In the case of AA and AC interactions both paral-lel (↑→) and ↑↓ holecules’arrangements are equally beneficial in terms of energy. The possi-bility of formation of molecular clusters-dimers is shown. It is concluded that these clusters are stabilized, in particular, by a dipole-dipole interaction of molecules.
