Photo‐Induced Stepwise Liquid Crystal Phase Transition Enabled by Hydrazone Photoswitch [PDF]
Advanced scienceA judiciously designed bistable hydrazone photoswitch enables a photo‐induced stepwise “order‐disorder” phase transition in liquid crystals. The linear‐to‐bent isomerization disrupts molecular packing, allowing precise tuning of phase transition temperatures.

Light-Driven Out-of-Equilibrium Helicity Control in a Diarylethene-Helicene Photosystem. [PDF]
Angew Chem Int Ed EnglDistinct energy landscapes of different helicities in the open and closed states of a diarylethene–helicene photoswitch enable a light‐driven energy ratchet. Helix inversion occurs selectively in the closed form, and the resulting helicity is transferred and kinetically trapped upon ring opening, generating a persistent out‐of‐equilibrium chiral state ...
