Photoinduced Electron Transfer (PET) as Key to Accelerate the Cycloreversion Reaction of Arylquadricyclanes

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
It is demonstrated that the photoinduced cycloreversion of a methoxynaphthylquadricyclane in the presence of suitable photocatalysts gives quantitatively the corresponding norbornadiene. As this photochromic norbornadiene‐quadricyclane cycle has favorable properties for light energy conversion, this method provides a useful tool for the targeted ...

Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks

Angewandte Chemie International Edition, Volume 65, Issue 29, 13 July 2026.
A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

Tetrazine Ligation in Living Systems: Beyond Fast Kinetics to Effective Bioorthogonality

Chemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.
Rapid reaction kinetics (k2) alone do not ensure successful tetrazine ligation in living systems. This review introduces ‘effective orthogonality’—focusing on chemical survival, availability, and encounter—as a practical framework. We highlight how bottlenecks shift from cellular sinks to in vivo delivery limits, offering design strategies for reliable

Light‐Induced Anion Translocation to Control Helical Folding in an Artificial Communication System

Chemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.
Anion‐induced helical folding of an oligomer is controlled indirectly and reversibly by light through anion uptake/release by a photoresponsive receptor. Thus, a light signal is processed into a chemical signal in a communication‐type three‐component supramolecular system.
