摘要: A simple and efficient procedure for the synthesis of three new series chalcogen liquid crystals, based on selenides diselenides, containing cholesterol in their structure, is described. Thermal crystalline properties were investigated by POM, DSC, TGA XRD scattering. Six nine molecules synthesized showed crystal properties, with smectic mesomorphism. All compounds presented good thermal stability. The mesomorphism was confirmed through analysis. morphology surface films using atomic force microscopy (AFM). prepared diselenides glutathione peroxidase like activity one 3.3 times more active than standard Ebselen.
