An Efficient Asymmetric Synthesis of a Liquid Crystal

A synthesis of L-(-)-4-(2-methylbutyl)phenyl4'-(2-methylbutyl)biphenyl-4-carboxylate (CE2) and of related chiral liquid crystals has been reported; nevertheless, a detailed experimental and spectrometric characterization of both the intermediates and the final product has been lacking in the literature.We present here the first synthesis of the enantiomer of CE2 with full experimental details including spectroscopic data for each of the intermediates.The description of the synthesis of (R)-(+)-2-methylbutanyl will be broadly useful for preparing other liquid crystals with optically active (R)-2-methylbutyl side chains.

MESOMORPHIC TRANSITION TEMPERATURES AND VISCOSITIES FOR SOME CYANO-BIPHENYLS AND -p-TERPHENYLS WITH BRANCHED TERMINAL ALKYL GROUPS.

A number of 4-alkyl- and 4-alkoxy-4 prime -cyanobiphenyls and 4-alkyl-4 double prime -cyano-p-terphenyls with branched chains were prepared. Marked depressions in the liquid crystal transition temperatures were observed relative to those for the corresponding n-alkyl derivatives, although the melting points were affected to a smaller extent. The viscosities of 10 wt% solutions of the individual branched-chain materials in the commercial mixture E7 were determined at 0 degree C and 20 degree C and substantial increases in the measured bulk viscosities were recorded.
