Abstract

Abstract: The phase transitions of a new group of mesogens, 2-(4-alkoxyphenyl)-6-substituted benzothiazoles were thermodynamically studied by DSC, and their transition temperatures and enthalpy changes were measured, from which the transition entropy changes were calculated. The results obtained were discussed. In addition, the phe-nomenon of super-cooling of the compounds were quantitatively observed.

Key words: Differential Scanning Calorimetry, Liquid crystal, Phase transition parameters, 2-(4-alkoxyphenyl)-6-substituted benzothiazoles
