Abstract
Tbe thermodynamic properties of two liquid crystals derived from chole sterol, namely the phenyl-thiocarbonate of cholesteryl and the 2,4-die thyl-phenyl-thiocarbonate of cholesteryl, were characterised by the di fferential scanning calorimetry (DSC) and by the thermomicroscopic met hod. The thermal parameters and some thermodynamic functions associate d to polymorphic transitions were determined, in correlation with thei r molecular bases.
