Angewandte Chemie, EarlyView.Reducing a nitro‐derivatized arylimido‐polyoxometalate (POM) reversibly switches on its second‐order NLO response, contrasting with prior donor‐functionalized systems that switch off upon reduction. Attenuation of charge‐transfer (CT) to the POM upon reduction gives a more strongly dipolar imido/π‐bridge to ─NO2 CT, signal enhancement of up to 15× (β ...

Angewandte Chemie, EarlyView.The excited‐state antiaromaticity of hydroxybenzotropyliums (HBTs) can be tuned through substituent effects to bring the aromatic ‘enol’ (E) and keto (K) tautomers close in energy. This leads to abnormally slow excited‐state proton transfer (on the ns timescale), giving rise to dual fluorescence emission and weak photoacidity.

Advanced Science, EarlyView.A supramolecular chirality evolution strategy in chiral low‐bandgap fused‐ring conjugated molecules enables high‐performance near‐infrared (NIR) circularly polarized light photodetection. Halogen substitution and thermal annealing induce chiral amplification and hierarchical ordering. Integrated into Schottky barrier vertical transistors, the optimized

Advanced Science, EarlyView.This work demonstrates a novel energy regulation strategy using the long‐lived S₁ state as a “kinetic capacitor” to achieve temporally decoupled integration of photoinduced deformation and multicolor fluorescence in naphthalimide‐functionalized carbon dots. This dual‐channel programmable shunting of excited‐state energy establishes a dynamic single‐use
