A new liquid crystalline (LC) phase with uniform tilt , local polar order and capability of symmetry breaking is found for a bent‐core mesogen combining a 4‐cyanoresorcinol unit with two azobenzene wings. The combination of local polar order and long range synclinic tilt in this SmC s P R phase leads, under special conditions, to macroscopic domains with opposite chirality, though the molecules themselves are achiral.
