Greener Solvents for the Photoisomerization and Catalytic Heat Release of a Norbornadiene‐Based Molecular Solar Thermal Energy Storage System [PDF]
Advanced Science, EarlyView.A Molecular Solar Thermal (MOST) system combining a scalable norbornadiene–quadricyclane photoswitch, a biodegradable solvent, propylene carbonate, and noble and first‐row metal catalysts, is presented. Propylene carbonate boosts photoisomerization quantum yield by 25% compared to toluene, prolongs energy storage by an additional 15 days, and enables ...

Photo‐Induced Stepwise Liquid Crystal Phase Transition Enabled by Hydrazone Photoswitch [PDF]
Advanced Science, EarlyView.A 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]
Angewandte Chemie, EarlyView.Distinct 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 ...

Optical Control of the Glucocorticoid Receptor Activity With a Photoswitchable Agonist [PDF]
Angewandte Chemie, EarlyView.A photoswitchable glucocorticoid receptor agonist enables optical control of receptor activity, achieving picomolar potency and partial agonism that preferentially maintains anti‐inflammatory signaling over canonical transcriptional activation. ABSTRACT Glucocorticoids (GCs) are widely prescribed anti‐inflammatory agents whose clinical utility is ...

Design of a Photoswitchable Cadherin [PDF]
Journal of the American Chemical Society, 2013 There is a growing interest in engineering proteins whose function can be controlled with the spatial and temporal precision of light. Here, we present a novel example of a functional light-triggered switch in the Ca-dependent cell-cell adhesion protein E-cadherin, created using a mechanism-based design strategy. We report an 18-fold change in apparent

Enlightening Materials with Photoswitches [PDF]
Advanced Materials, 2020 Abstract Incorporating molecular photoswitches into various materials provides unique opportunities for controlling their properties and functions with high spatiotemporal resolution using remote optical stimuli. The great and largely still untapped potential of these photoresponsive systems has not yet been fully exploited due to the
