Solvent effects on photodegradation of CI Reactive Orange 16 by simulated solar light [PDF]
Hemijska Industrija, 2008 Organic solvents may appear in wastewaters and other industrial waste streams containing dyes, therefore, their photodegradation catalyzed by TiO2 should be investigated.

2,5-PRODAN Derivatives as Highly Sensitive Sensors of Low Solvent Acidity
Molecules, 2014 Two 5-acyl-2-dimethylaminonaphthalene derivatives, one with a propionyl group and the other with a fused cyclohexanone ring, are investigated as sensors of H-bond-donating ability in protic solvents of low solvent acidity.

Hydrogen-Bonded Encapsulation Complexes in Protic Solvents
, 2016 We describe here the behavior of the hydrogen-bonded capsule 1·1 and its complexes in protic solvents. The kinetics and thermodynamics of the encapsulation process were determined through conventional 1H NMR methods.

Unprecedented high fluorescence anisotropy in protic solvents: hydrogen bond induced solvent caging?
, 2016 Atypical high fluorescence anisotropy has been revealed in protic solvents for excited state intramolecular proton transfer (ESIPT) prone 3-hydroxyflavone and some of its hydroxy derivatives. In non-protic solvents, however, the anisotropy values are low.
