Abstract

Abstract This work illustrates how minor structural perturbations produced by methylation of 4′-(dodecyloxy)-4-cyanobiphenyl leads to enthalpy–entropy compensation for their melting processes, a trend which can be analyzed within the frame of a simple intermolecular cohesive model. The transformation of the melting thermodynamic parameters collected at variable temperatures into cohesive free-energy densities expressed at a common ...
