  Liquid Crystalline Behavior of Binary Mixtures of Structurally Dissimilar Mesogens and Nonmesogens

  摘要：

  We have studied eight binary systems comprising three enantiotropic nematogens, namely 4-(4-n-butyloxybenzoyloxy)phenylazo-4-fluorobenzene, 4-(4-n-butyloxybenzo yloxy)benzylidene-4-fluoro aniline, and 4-(4-n-heptyloxybenzoyloxy)phenylazo-4-fl uorobenzene; a monotropic nematogen, viz. 4-(4-n-dodecyloxybenzoyloxy)napthylazo-4-fluorobenzene; and three nonmesogens, viz. 4-(4-n-butyloxy benzoyloxy)benzalde hyde, 4-methoxybenzylidene-4-chloroaniline, and 4-methoxybenzylidene-4-toluidine. The central linkage, terminal group, and central ring system of the components have been varied systematically and the effect of these variations has been evaluated on the liquid crystalline properties of the binary mixtures. The mixed mesomorphic properties of these systems are discussed on the basis of their phase diagrams.

• Effect of Lateral Substitution on Mesogenic Properties of Fluoro Aniline Derivatives

  Three new homologous series of liquid crystals with terminal fluoro group and central linkages such as ester and azo groups were synthesized and their mesomorphic properties were studied. All three series are similar in molecular structure with the difference in their lateral substitutions: series I has no lateral substitution, series II has a chloro group as lateral substitution, and series III has a methyl group as lateral substitution. All 12 homologues of each of the series are mesogenic in nature. The nematic phase of the series shows a marble texture and the smectic phase shows a Schlieren texture of the smectic C variety. The mesomorphic characteristics of the series are compared with each other.
