In search of novel photoactive liquid crystals, we have synthesized a series of five-ring pyridine-based bent-core compounds bearing different substituents at the peripheral phenyl rings (CH3O, Cl and NO2). Their mesomorphic behaviour has been investigated by polarizing optical microscopy, differential scanning calorimetry and X-ray scattering, and then compared with the unsubstituted parent compound. The introduction of the methoxy groups at the peripheral phenyl rings of the bent core results in a non-mesomorphic compound, whereas the chloro- and nitro-substituted compounds form enantiotropic B1-like phases. Significant changes in the textures and transition temperatures of the mesophase have been observed under UV light. The present investigation of the mesomorphic properties of the synthesized compounds, coupled with the analysis of the molecular packing of the related three-ring compounds, will help design self-organized molecules suitable for UV indicators.

Bent-core mesogens have gained considerable importance due to their ability to form new mesophases with unusual properties. Relationships between the chemical structure of bent-core molecules and the type and physical properties of the formed mesophases a

Disclosed is a mesomorphic compound having a β-hydroxycarboxyl group as the chiral source, which is represented by the formula: STR1 wherein m and n are integers of from 1 to 18, X1 and X2 independently represent fluorine, chlorine or hydrogen, Y represents STR2 or --O--, Z represents a direct bond, STR3 --CH hd 2O-- or --OCH2 --, and * indicates the asymmetric carbon. The mesomorphic compound is valuable as a ferroelectric liquid crystal or an additive to a ferroelectric liquid crystal or to a compound showing the SmC phase and having no chiral group.
