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

Absorption spectra of 6-aminocoumarin (6AC) and 7-aminocoumarins (C120 and C151)
were studied in polyfluorinated alcohols:(1, 1, 1, 3, 3, 3-hexafluoroisopropanol (HFIP), 2, 2, 2 …

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 …

The change in the electronic absorption and emission energy of 7-aminocoumarin
derivatives in binary solvent mixtures has been studied. The electronic transition energy …

Bi-and triexponential and emission-wavelength-independent fluorescence decays have
been observed for the 7-aminocoumarins C1 andC102 in several polar solvents. An …

The steady state absorption and emission spectra of biologically active iodinated 4-
aryloxymethyl coumarins 4-(4-iodo-phenoxymethyl)-benzo [h] coumarin (4IPMBC) and 4-(4 …

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

We have studied the solvation statics and dynamics of coumarin 153 and 102 dyes in
hexane− methanol mixtures. The solvation of the coumarin dyes, both in the ground and in …

Solvent density dependence of the absorption and fluorescence spectra of coumarin 153 in
argon (Ar), ethane (C 2 H 6), carbon dioxide (CO 2), and trifluoromethane (CF 3 H) has been …

The photophysical properties of 7-amino-4-trifluoromethyl-1, 2-benzopyrone (coumarin-151;
C151) in nonpolar (NP) solvents are drastically different than those in other solvents of …
