Abstract

Calorimetric measurements have been done to investigate the smectic-C*α(SmC*α)- smectic-C*(SmC*) transition using high sensitivity differential scanning calorimetry. It was found that the SmC*α-SmC * transition for a liquid crystalline compound 11OHFBBB1M7 shows a first-order transition with a clear thermal hysteresis while other two compounds, LN36 and 12OTBBB1M7, exhibit continuous behaviors which support the existence of the critical point and also the slow relaxation dynamics encountered with the change in the helical pitch.
