✦ Synopsis
The tilted smectic liquid‐crystal phase of an ester‐based bent‐core mesogen (see Figure) is optically isotropic due to the combination of suitable tilt and opening angles of the bent cores. In electric fields, V‐shaped switching between isotropic and birefringent states is observed. Both the antiferroelectric and ferroelectric states consist of optically active domains due to the twisted molecular structure.
