The ground-and excited-state protonation of Coumarin 102 (C102), a fluorescent probe
applied frequently in heterogeneous systems with an aqueous phase, has been studied in …

Coumarin 183 (C183) was used as a photoacid to study excited-state proton transfer (ESPT)
reactions. Here, we studied the effect of ions on the ESPT of C183 in aqueous NaCl …

Preferential solvation of solvatochromic probe coumarin 153 has been studied in toluene−
acetonitrile and toluene− methanol solvent mixtures. Solvatochromic shifts of absorption and …

Molecular dynamics simulations are applied to the preferential solvation of coumarin 153
(C153) by alcohol in an alcohol/alkane mixture, indicated by recent steady-state and time …

Fluorescence up-conversion measurements were conducted to investigate the solvation
dynamics of a deprotonated coumarin 343 (C343) in a solution of CH3ONa CH3OH. In the …

Static and time-resolved fluorescence techniques are employed to measure the solvation
statics and dynamics of electronically excited coumarin 153 in several …

Oxoaromatic compounds are known to be weak organic bases. In the ground electronic
state they are protonated in very acidic media (pH< 0)[1-4]. On excitation the basicity of …

We have studied the solvation statics and dynamics of coumarin 153 dye in binary hexane−
propionitrile solvent mixtures. The static and dynamic solvation of coumarin 153 in hexane …

We present results of molecular dynamics simulations of solvation dynamics of coumarin
153 in dimethylsulfoxide (DMSO)–water mixtures of different compositions (x D= 0.00, 0.25 …

The steady-state absorption and emission as well as the time-resolved fluorescence spectra
of coumarin 102 (C102) in both aprotic and alcoholic solvents have been used to study the …
