Fluorinated azobenzenes as supramolecular halogen-bonding building blocks

Beilstein Journal of Organic Chemistry, 2019
ortho-Fluoroazobenzenes are a remarkable example of bistable photoswitches, addressable by visible light. Symmetrical, highly fluorinated azobenzenes bearing an iodine substituent in para-position were shown to be suitable supramolecular building blocks ...

Optically Switchable Full‐Color Quantum Dots via Diarylethene Photoswitches for Smart Display and Security

SmartMat, Volume 7, Issue 1, February 2026.
An innovative photoswitchable system based on quantum dots and diarylethene enables reversible RGB photoluminescence switching. The system achieves over 90% photoluminescence quantum yield in the on state and a high on/off ratio of ~100. Efficient switching is driven by synergistic Förster resonance and triplet energy transfer, applicable for ...

Designing Chimeric LOV Photoswitches

Chemistry & Biology, 2012
The LOV domain from Avena sativa has a C-terminal (Jα) helix that dissociates and unfolds when the protein is exposed to blue light. Using computational protein design methods, Lungu et al., in this issue of Chemistry & Biology, created chimeric Jα sequences that show photo-controlled interactions with chosen targets.

Optochemical modulation of corneal cold nerve terminal impulse activity with a photochromic ion channel blocker

British Journal of Pharmacology, Volume 183, Issue 3, Page 545-559, February 2026.
Background and Purpose The functional organization of corneal cold nerve endings, critical structures in maintaining the ocular surface, remains poorly understood. Here, the photoisomerizable small‐molecule diethylamine‐azobenzene‐quaternary ammonium (DENAQ) was used to photomodulate activity of cold‐sensing nerve terminals in control and chronic tear ...
