Introduction of lateral intermolecular interactions (dipole-dipole interactions, hydrogen bonds, and perfluoroarene-arene interactions) are attempted in rodlike and half-disklike molecules. In the cases of dicyanothiophenes, introduction of long cores stabilized their liquid crystal phases to give smectic and columnar phases, though the large lateral dipole in short rodlike molecules suppressed the molecular movements to destabilize the liquid crystal phases. Trialkoxybenzoic anhydrides were also organized into columnar aggregates by intermolecular dipole-dipole interaction. Further, molecules introduced a large lateral dipole at the center were useful for phase transition from smectic C to smectic CA phase. On the other hand, introduction of intermolecular hydrogen bonds in the direction of the molecular short axis generated novel smectic and cubic phases with strong hydrogen bonding. In the case of the liquid crystalline ureas, a switching behavior of the polarities was observed. Perfluoroarene-arene interaction was also useful to organize small molecules into a columnar superstructure.
