New coumarin esters, (E)-4-[[[7-(octyloxy)-2-oxo-2H-chromen-3-yl]imino]methyl]phenyl-4-alkyloxybenzoates, containing a Schiff base linkage in which an octyloxy chain is at one end and different long terminal alkoxy chains (C2-C18) are at the other end, have been synthesized and studied for their mesomorphic behavior. The investigation of phase and mesophase transitions was carried out using differential scanning calorimetry and a Polarized Optical Microscope. The mesomorphic investigation revealed that all new derivatives exhibited an enantiotropic nematic phase and, except for two compounds, I [R = CnH2n+1, n = 2, 3], all the members also displayed enantiotropic smectic C phase in addition to enantiotropic nematic phase. The new mesogens mesomorphic behavior of all synthesized compounds were thoroughly studied and discussed, as well as compared with structurally comparable substances. Finally, the DFT theor. calculations were studied and compared with the exptl. to explain the relationship between the structural parameters and the mesomorphic behavior.
