Photodissociation of Cl_2O at 248 and 308 nm [PDF]
, 1997 Molecular beam studies of Cl_2O photolysis at 248 and 308 nm have been repeated and the analysis refined. At 248 nm, three distinct dissociation pathways that led to Cl+ClO products were resolved.

Controlling Competitive Radical Pathways: Insights from Aryl Diazonium Electrografting
Chemistry – A European Journal, EarlyView.This work shows that nitrobenzene diazonium electrografting results from competition between aryl and diazenyl radicals, which govern film composition. Using simulations and control strategies, grafting conditions are tuned to favor specific radicals. It enables selective formation of azo‐enriched films and paves the way toward the precise control of ...

Fluorescent Diarylethenes With Polar Groups: Synthesis, Spectra, and Optical Microscopy Applications
Chemistry – A European Journal, EarlyView.Blinking green and flashing red: photo‐switchable and photo‐activatable probes emitting green and red light were prepared and applied as bioconjugates in super‐resolution optical microscopy. ABSTRACT The use of photoactivatable fluorescent diarylethenes (fDAEs) in biology‐related light microscopy has been restricted by the lack of probes having freely ...

Photocatalytic Degradation of PFOA with Porous Lanthanoid Perovskites Nano Catalyst
Chemie Ingenieur Technik, EarlyView.Photocatalytic degradation of PFOA was studied using nickel‐ and lanthanide‐doped perovskites under UV–VIS irradiation. Catalyst characterization confirmed successful doping, with Ni/NdMnO3 showing the highest photocatalytic efficiency. Degradation occurred via C–C bond cleavage, forming transformation products PFHpA and PFHxA.

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐
