The high pressure phase behaviour of four liquid crystals, belonging to the
class of laterally aryl-substituted mesogens has been studied with differe
ntial thermal analysis. The pressure dependence of the phase transitions ha
s been determined up to 300 MPa. Transition enthalpies have been determined
with the aid of differential scanning calorimetry. Volume changes accompan
ying the phase transitions have been calculated using the Clausius-Clapeyro
n equation. Several metastable phase transitions have been discovered.
