Innenrücktitelbild: Reversible Handedness Inversion and Circularly Polarized Light Reflection Tuning in Self‐Organized Helical Superstructures Using Visible‐Light‐Driven Macrocyclic Chiral Switches (Angew. Chem. 8/2023)

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 switch.
