A simple and efficient procedure for the synthesis of three new series of chalcogen liquid crystals, based on selenides and diselenides, containingcholesterol in their structure, is described. Thermal and liquid crystalline properties were investigated by POM, DSC, TGA and XRD scattering. Six of the nine molecules synthesized showed liquid crystal properties, with smectic mesomorphism. All the compounds
