A phase transition study for two homologues of the terephthalylidene bis-4-n-alkylanilines

Abstract

The variation of density with temperature across different phases for two homologues of the terephthalylidene bis-4-n-alkylaniline series (TBAA7 and TBAA9) was determined to locate the phase transitions. The temperature dependence of the thermal expansion coefficient and the estimated pressure dependence of the transition temperatures together with the reported experimental P-T data are discussed.
