Abstract

Two series of fluorinated Schiff's base esters have been synthesized and characterized. Their chemical structures were identified by FTIR, 1H NMR, and elemental analysis (EA). Their mesomorphic properties were studied by polarizing optical, microscopy (POM) and differential scanning calorimeter (DSC). It was found that most of the compounds with alkyl end group exhibited enantiotropic smectic A and nematic phase; while that with alkoxyl ...
