Synthesis and mesomorphic properties of laterally fluorinated alkyl 4′′-alkylterphenyl-4-yl carbonate liquid crystals

Fifteen series of homologues of a variety of mono-, di- and trifluorosubstituted alkyl 4′′-alkylterphenyl-4-yl carbonates have been synthesized and their mesomorphic properties have been determined. From among 95 prepared compounds, 40 pure nematogens have been found, as well as 55 mesogens with orthogonal and tilted smectic phases in broad temperature ranges. The type and combination of the LC phase strongly depend on the position and number of the fluorine atoms. Physical properties and correlations between the molecular core fluorosubstitution, the length of the terminal chains and the type and sequence of the liquid crystalline phases, have been determined. The compounds are useful for the formulation of nematic mixtures as well as ferroelectric ones.

Synthesis of Isocyano and (Haloalkynyl)Biphenyls: New Thermotropic Liquid Crystals

4-n-Alkyl-4'-cyanobiphenyls (1) have achieved widespread application as stable thermotropic liquid crystals with mesophases at room temperature.The importance of the cyano group in the liquid-crystalline behaviour of these compounds is not clearly defined.By modifying this functional group with minimal changes in molecular geometry, we have found two new classes of mesomorphs, 4-n-Alkyl-4'-isocyanobiphenyls (2) and 4-n-alkyl-4'-(haloalkynyl)biphenyls (3).The synthesis of these compounds is described.Compound 2a (R = n-butyl) is non-mesomorphic, whereas compound 2b (R = n-pentyl) is a virtual liquid crystal melting at 34-5 deg C and supercooling to a nematic phase at 30 deg C, and 2c (R = n-hexyl) is a nematic liquid crystal from 9 to 19 deg C.Compounds of structure 3 (R = n-pentyl, X = Si(CH3)3, H, CH3, Cl) are not liquid crystals.The corresponding bromo- and iodoalkynes (3, R = n-pentyl, S = Br, I) are liquid crystals with mesomorphic ranges of 88-108 deg C and 110-119 deg C, respectively.

Effect of Bonded-Chain Rigidity on Selectivity in Reversed-Phase Liquid Chromatography

A model stationary phase has been synthesized and used to test the predictions of a lattice-model-based, unified molecular theory for selectivity in reversed-phase liquid chromatography recently proposed by Martire and Boehm.The results of the measurement of selectivity for flexible-chain, rigid-rod, and platelike solutes support the predictions of the model with selectivity following the order rods > plates > flexible chains.
