Abstract
A series of Schiff base ester, 4-{[(4-iodophenyl)imino]methyl}phenyl alkanoates possessing different number of carbon atoms at the terminal alkanoyloxy chain (Cn-1H2n-1COO-, n = 4, 6, 8, 10, 12, 14) was synthesized. C4 member was found non-mesogenic, whilst C6 to C14 derivatives exhibited enantiotropic smectic A phase with fan-shaped texture. It was found that the length of terminal alkanoyloxy chain influenced the mesomorphic properties.
