First symmetrical banana compounds exhibiting SmAP(R) mesophase and unique transition between two orthogonal polar phases.
Novel banana-shaped liquid crystals with stilbene bridges were synthesized. All presented materials exhibit the polarization-randomized non-tilted smectic phase (SmAP(R)) in a broad temperature range and the antiferroelectric non-tilted smectic phase (SmAP(A)) at room temperature.
