Gomola, Kinga published the artcileAn optically uniaxial antiferroelectric smectic phase in asymmetrical bent-core compounds containing a 3-aminophenol central unit, Formula: C7H9NO, the publication is Journal of Materials Chemistry (2010), 20(37), 7944-7952, database is CAplus.
Two series of asym. bent-core compounds possessing 3-aminophenol and its N-Me derivative have been synthesized. The asymmetry arose from the different linkages between the central unit and the chem. chains of the substituents, and in two cases also from different lateral substituents. The mesomorphic properties were investigated by differential scanning calorimetry, polarizing optical microscopy, switching current and electro-optical measurements, X-ray anal., and second-harmonic generation. All materials possessing 3-aminophenol as a central unit showed liquid crystalline properties, and two of them exhibited the orthogonal smectic phase (SmA family phase) and very stable columnar phases, while the N-Me analogs exhibited no mesophase. Because of the optically uniaxial nature, double switching current peaks, and SHG activity associated with a distinct threshold elec. field, this orthogonal smectic phase was assigned to a novel type, which has a short-range antiferroelec. order with a long-range randomized polar plane (SmAPAR).
