Abstract
Three selected compounds with a rich liquid crystalline polymorphism of chiral tilted smectic phases were investigated with respect to their pyroelectric behaviour. Measurements for well aligned samples are presented with high temperature resolution and are compared to the calorimetric behaviour. Data of the temperature dependence of the spontaneous polarization is derived for all smectic phases under investigation and compared to the behaviour obtained for the smectic C* phase by the triangular wave method.
