Intercalated liquid-crystalline phases formed by symmetric dimers with an α,ω-diiminoalkylene spacer

Four series of symmetric, dimeric molecules with flexible α,ω-diiminoalkylene spacers have been synthesised and characterised by polarising optical microscopy, differential scanning calorimetry, and X-ray diffraction. The effects on the mesomorphism of th

Liquid crystalline behavior of binary mixtures of structurally dissimilar mesogens and nonmesogens

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.

Synthesis, characterization and mesomorphic properties of new rod-like thiophene based liquid crystals

Two new mesogenic homologous series of Schiff base esters, 2-[4-(4-n-Alkoxy benzoyloxy) benzylidenamino] 3-cyno thiophine (Series-A) and Schiff base cinnamates, 2-[4-(4-n-alkoxy cinnamoyloxy) benzylidenamino] 3-cyano thiophene (Series-B), comprising a thiophene moiety were synthesized. Structural elucidation was carried out using elemental analysis and spectroscopic techniques such as FT-IR, 1H-NMR and 13C-NMR, and mass spectrometry. The mesomorphic properties and thermal stabilities of the title compounds were studied by using differential scanning calorimetry and optical polarizing microscopy. All the derivatives are mesomorphic in nature showing the nematic phase, and the higher members of Series-A show a smectic C phase whereas Series-B exhibits only the nematic mesophase. The mesomorphic properties of the present series are compared with other structurally related compounds. Taylor and Francis Group, LLC.
