Switching signs : The polar structure of a tilted smectic C phase formed by a homologous series of bent‐core mesogens changes from antiferroelectric to ferroelectric with increasing chain length. The polar switching of the banana‐shaped molecules occurs by collective rotation around their long molecular axes (a) or by rotation of the director around the tilt cone (b). Red and blue designate layers of opposite chirality.
