Unusual mesomorphic behaviour has been found in a series of rod-like liquid crystalline (LC) compounds with two chiral centres in the molecular chain. A re-entrant paraelectric SmA* phase has been discovered below the ferroelectric SmC* phase on cooling for one homologue. So far this compound is the only one exhibiting the re-entrancy of the smectic A phase in chiral LC system with structural parameters so close to the upper SmA* phase.
