A series of asym. bent-core liquid crystals I (X = COO; Y = H, Cl), bearing the stilbene moiety in the side wing, was synthesized and characterised. Structural modifications of the non-stilbene wing resulted in formation of various mesophases. Compounds I (X = COO; Y = H) and I (X = COO; Y = Cl) with an ester linking group between the Ph rings in this wing have an enantiotropic non-polar smectic-type mesophase, while compound I (Y = H), incorporating the biphenyl moiety, has a ferroelec. SmCaPF phase. The mols. of I (Y = H) undergo photoisomerisation in solution under UV irradiation, while the mesophases are unstable and UV irradiation leads to irreversible changes. The mesophases of I (X = COO; Y = H) and I (X = COO; Y = Cl) do not show any electro-optical switching and polarisation current. Applying low frequency AC voltage on a planarly aligned film of compound I (Y = H), smectic domains grow, while the birefringence and an image flickering increase. The observed features of these compounds identify stilbene as an attractive moiety in the design of advanced materials based on bent-core mols.
