The spontaneous polarization (P s) induced by chiral dipolar additives in non-chiral smectic C liquid crystals was investigated. High values of Ps , are reported. A special type of smectic polymorphism was observed and novel phases, supposedly, of the anti-ferroelectric type were discovered. Fast linear electro-optical switching with low-temperature mixtures was demonstrated.
