The mixts. studied consisted of 2 terminal polar liq. crystals which show phase induction with the requirement that polar electron-donating and electron-accepting components to a pi system be present. Two nitriles were mixed with 3-phenylcyclohexane and 2-biphenyl derivs. All the substit- uted anilines, including N-substituted derivs., showed induced smectic mesomorphism or an induced solid phase at high concn., and expansions of the nematic range of the nitrile at <7wt%. Phase diagrams of 2 systems are given. Interactions between liq. cryst. mols. of an electronic nature can perturb the normal phase relations whether these are dipole-dipole or charge-transfer type.
