A series of macrocyclic azobenzene‐based chiral photoswitches have been judiciously designed, synthesized, and characterized. In the molecular structures, binaphthyl is covalently linked to ortho‐positions of azobenzene, and four different substituents are linked to 6,6′‐positions of binaphthyl. The photoswitches show enhanced helical twisting power (HTP) when doping in commercially available achiral...
Reversible handedness inversion is achieved in self‐organized helical superstructures using a visible‐light‐driven macrocyclic chiral switch, as reported by Quan Li and co‐workers in their Research Article (e202216600). Green and blue light can drive the reversible switching between left‐ and right‐handedness via the reversible cis/trans photoisomerization of azobenzene within the cyclic molecular...
