Photoresponsive Cyanostilbene Bent‐Core Liquid Crystals as New Materials with Light‐Driven Modulated Polarization

Two isomeric cyanostilbene photoswitchable bent-core mesogens with polar liquid crystal phases in which macroscopic polarization and luminescence can be light-modulated are introduced. Z/E isomerization or [2+2] cycloaddition photochemical processes occur depending on the chemical structure, which make the compounds very innovative multifunctional advanced materials.
