Two series of liquid crystalline systems comprising [4-(cholesteryloxycarbonyl)phtalimide] acetic acid esters of several poly(ethylene glycol) methyl ethers or aliphatic alcohols have been synthesized and studied by means of DSC, polarized optical microscopy and X-ray diffraction methods. All compounds form the chiral nematic phase N*. It nas found that the esterimides with oxyethylene tails form additionally the chiral smectic C* phase. its layer distances show a bilayer stacking likely to result from microsegregation among polar and nonpolar parts of the molecules. In the case of mesogens with methylene tails the monolayer smectic A phase has been observed.
