H. Kihara et al., SUPRAMOLECULAR FERROELECTRIC LIQUID-CRYSTALS - HYDROGEN-BONDED COMPLEXES BETWEEN BENZOIC-ACIDS AND CHIRAL STILBAZOLES, Liquid crystals, 21(1), 1996, pp. 25-30
Supramolecular ferroelectric liquid crystalline complexes have been ob
tained from 4-alkoxybenzoic acids and optically active trans-4-substit
uted-4'-stilbazoles. Chiral smectic C phases are induced by the format
ion of supramolecular mesogenic structure through the selective interm
olecular hydrogen bond between the achiral benzoic acids and the chira
l non-mesogenic stilbazoles.
