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.

Novel liquid crystal compounds are disclosed, which are chiral esters based upon the phenol STR1 Typical examples are: STR2 and mixtures of these compounds have a helical pitch such that the mixtures reflect light of a specific wavelength when illuminated with ordinary light and the pitch is temperature sensitive so that the mixtures can be used in temperature indicating devices. Specific examples are given as are samples of mixtures that can be used in phase change electro-optic display devices.
