Synthesis of new esters, derived from cholesterol

In order to establish a corelation between thermal stability and molecular structure, it was synthesized nerv esters of cholesterol. The change in the rmal stability was investigated where oxygen in cholesteryl eaters of chole sterol. The change in thermal stability was investigated where oxygen in ch olesteryl eaters was replaced by sulphur. The new compounds were characteri sed by IR and NMR measurements. The texture of the mesophase has been deter mined with a polarising microscope equipped with a hot stage.
