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.

Phase Diagram and Preparation of CE2 Enantiomers

The synthesis of (L)-(-)-4"-(2-methylbutylphenyl) 4'-(2-methylbutyl)-4-biphenylcarboxylate (CE2) and related chiral liquid crystals has been discussed by Gray and McDonnell.We present here the first synthesis of the enantiomer of CE2 and we use it to measure the temperature-chirality phase diagram of the blue phases of CE2.This diagram is compared with that obtained using the CE2 "racemate" containing nonenantiomeric optical isomers of CE2.The synthesis of (R)-(+)-2-methylbutan-1-ol which has been developed will be broadly useful for the preparation of other chiral liquid crystals having optically active (R)-2-methylbutyl sidechains.

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.
