Synthesis and characterization of a new photoinduced switchable β-cyclodextrin dimer

Beilstein Journal of Organic Chemistry, 2014
This paper reports an efficient preparation of bridged bis-β-CD AZO-CDim 1 bearing azobenzene as a linker and exhibiting high solubility in water. The photoisomerization properties were studied by UV–vis and HPLC and supported by ab initio calculations ...

Molecular Preorganization Unlocks Reversible Solid‐State Photoconversion in Dianthrylnaphthalene‐Based Molecular Solar Thermal Systems

Angewandte Chemie, EarlyView.
Three dianthrylnaphthalenes were synthesized and investigated for molecular solar thermal (MOST) energy storage. Naphthyl‐based bridging units preorganize the two anthracene moieties face‐to‐face, leading to improved photoisomerization quantum yield (QY) and unlocked bidirectional photoswitching in the solid state compared to previously reported ortho ...

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Optical Control of the Glucocorticoid Receptor Activity With a Photoswitchable Agonist

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 ...
