Bistable Switching of π‐Conjugation in a Dithienylethene‐Bridged Luminescent Trityl Diradicaloid

Angewandte Chemie International Edition, Volume 65, Issue 43, 19 October 2026.
Photoswitches that affect π‐conjugation offer a powerful strategy for external manipulation of luminescent diradicals. Dithienylethene‐linked persistent trityl diradicaloids, DTE‐TTM2 and F6‐DTE‐TTM2, exhibit bistable switching of their optical, electrochemical and magnetic properties.

Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

Control of Gemcitabine Activity With Blue and Red Light

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
Treating cancer with chemotherapy is generally associated with many side effects, which can be addressed by selectively releasing the desired drugs with visible light. Sixteen new blue light‐activatable cytostatics were introduced, with the gemcitabine derivative exhibiting ideal properties.

Improvement of a calcium binding photoswitch through model studies

, 2014
The biological effects of calcium oscillations can be identified readily, but the mechanism giving rise to these effects on a molecular level has not been fully elucidated.

In Silico to In Cerebro—Development of the Orexin Receptor Antagonist “Photorexant” for Photomodulation In Vitro and in Mouse Brains

Angewandte Chemie International Edition, Volume 65, Issue 42, 12 October 2026.
Following a structure‐based design approach, photoswitchable derivatives of the FDA‐approved drug suvorexant were designed, docked, synthesized, and characterized pharmacologically at the orexin 1 and 2 receptors (OX1R and OX2R). Optimized “photorexant” showed up to an 11‐fold difference in IC50 between photoisomers, enabled dynamic and reversible ...
