Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A new liquid crystalline (LC) phase with uniform tilt</bold>, 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_sP_R phase leads, under special conditions, to macroscopic domains with opposite chirality, though the molecules themselves are achiral. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1xppb3v0" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
