| dc.description.abstract | New set of trifluromethyl, diethylamino and morpholino derived coumarin compounds were prepared by reacting various coumarin 3-carboxylic acids with various phenyl esters with peripheral alkyl, ester and polar cyano moieties in the presence of EDC.HCl/DMAP as esterification agent. The chemical structures of new coumarin derivatives were confirmed by standard spectroscopic techniques and mesomorphic behaviours were established by polarised optical microscopy (POM) and differential scanning calorimetry (DSC). Trifluoromethane and morpholino derivatives show SmA/Nematic phase, while diethylamino derivatives did not show liquid crystalline property. | en_US |
