Liquid crystalline behavior of two-component molecular adducts from bifunctional molecules-II
The phase behavior is reported for five two-component systems based on two different bifunctional molecular species (4,4'-(1-,4-butanedioxy)diphenol-bis(pyridinecarboxylate) and 4-acetylpyridinazine) characterized by the presence of pyridinic nitrogen and capable of interacting with carboxylic acids via hydrogen bond. The evidence of a drastic influence of this interaction in the solid and liquid phase is shown. For four systems, thermotropic liquid crystal behavior is found on the basis of differential scanning calorimetry and polarized optical microscopy at controlled temperature.
