Markides, K.E., Nishioka, M., Tarbet, B.J., Bradshaw, J.S., and Lee, M.L., Smectic biphenylcarbox-ylate ester liquid crystalline polysiloxane stationary phase for capillary gas chromatography, Anal. Chem., 57, 1296, 1985. 

A commercially available semetic phase composed of biphenylcarbox-ylate ester attached to the polysiloxane backbone of a fused silica column has been shown to be ideal for the separation of geometric isomers of polycyclic aromatics of various classes of compounds [14,15]. This column exhibits a wide semetic temperature range of 100-300°C and has been shown to be stable to at least 280°C. Liquid-crystal stationary phases have also been employed in SFC [16]. 

The thermal and Lewis acid catalyzed reactions of electron-deficient aldehydes such as chloral, glyox-ylate esters and phenylglyoxal have been extensively studied. The reactions with glyoxylate esters are particularly intriguing, since use of a chiral ester group has permitted these reactions to be carried out with excellent asymmetric induction.
