Hexatic and Crystal B Phases in a Series of Liquid Crystal Compounds

Microscopy and miscibility techniques have been used to identify the hexatic B and crystal B phases of three pure compounds belonging to the same series. The physical behavior of smectic A, hexatic B and crystal B phases of these compounds has been studied by differential scanning calorimetry and dilatometry. Results on the smectic A to hexatic B and hexatic B to crystal B phase transitions are presented.
