TL;DR: In this article, the acidity constants pKa(T) in the triplet state of aromatic ketones in H2O-CH3CN (4:1) mixtures have been studied by means of nanosecond laser flash photolysis.
Abstract: Acid–base properties in the triplet state of aromatic ketones in H2O–CH3CN (4:1) mixtures have been studied by means of nanosecond laser flash photolysis. The acidity constants pKa(T) in the triple...

TL;DR: Theoretical models that have been proposed and applied to proton transfer reactions are reviewed in this paper, where simple models, like the Eigen model, Marcus theory and the intersecting state model, are applied to excited-state intermolecular proton transfers.
Abstract: Theoretical models that have been proposed and applied to proton transfer reactions are reviewed in this work. Simple models, like the Eigen model, Marcus theory and the intersecting state model, are applied to excited-state intermolecular proton transfers. The kinetics and thermodynamics of proton transfers occuring in the singlet states of aromatic molecules with OH, NH3+, NH2 and CO substituents are reviewed.

TL;DR: This Critical Review discusses recent growth areas in fluorescent PET sensors by emphasizing the modular features of the 'fluorophore-spacer-receptor' design by critically examined as a case in point.
Abstract: Fluorescent sensors are an important part of the analytical scientist's toolbox. The use of fluorescent PET (Photoinduced Electron Transfer) sensors has seen particular growth in recent times. This Critical Review discusses recent growth areas in fluorescent PET sensors by emphasizing the modular features of the ‘fluorophore–spacer–receptor’ design. The occurrence of the dipicolylamine receptor in PET sensor designs is critically examined as a case in point.
