- Description
- We discuss the synthesis and characterisation of new non-symmetric liquid crystal dimers of cholesteryl n-(4-formyl-2-methoxyphenoxy)alkanoates by tethering cholesterol and vanillin. Spectroscopic characterisation such as IR, 1H and 13C NMR used to confirm the molecular structures. Mesophase properties are assessed using polarising optical microscopy (POM) and differentially scanning calorimeter (DSC). All the dimers in the series display liquid crystalline phase particularly cholesteric and smectic A* phases. Additionally, a UV-Vis study showed that the molecules self-assemble into H-aggregates with strong fluorescence emission. DFT studies provide insights into molecular geometry, electronic structure, and energy states, enabling detailed estimations of chemical behaviour and interactions. 2025 Informa UK Limited, trading as Taylor & Francis Group.
