Liquid/single crystal structure analysis: Synthesis and characterization of a trimethylsilyl derived rod shaped mesogen
4-[4′-Cyanophenoxy-carbonyl-phenyl-4-(trimethylsilyl)ethynyl]benzoate a rod shaped liquid crystal (SmA) is synthesized and characterized. The single-crystals were grown in triclinic crystal system in the space group of P1ˉ - with unit cell parameters a =
Chemoselective hydrolysis of ester bonds in the presence of Baker's yeast
The catalytic effect of baker's yeast on the hydrolysis of aliphatic esters in p-acetoxybenzoates is described. The chemoselective character of this reaction enables the selective protection of the hydroxyl group in p-hydroxybenzoic acid derivatives.

Biaxial smectic A phase in homologous series of compounds composed of highly polar unsymmetrically substituted bent-core molecules
Several compounds belonging to three new series of five-ring banana-shaped esters, which are unsymmetrically substituted with respect to the central phenyl ring, have been synthesised. One of the arms of these bent-core molecules has been terminally subst
