Abstract

The behaviour of solvatochromic absorbance probes within binary mixtures of TX-100/organic solvents.

Unraveling the effect of solvents on the excited state dynamics of C540A by experimental and theoretical study

“…[6][7][8][9] To explore the inuence of intermolecular hydrogen bonds on the excited-state dynamics, [10][11][12][13][14][15] the Kamlet-Ta (K-T) solvatochromic parameters (p*, a, b) have been developed to depict the hydrogen bond interaction between solute and solvent molecules and to depict the spectral redshi in the steady-state absorption and uorescence spectroscopy induced by solvents. [16][17][18][19] For instance, Horng et al studied the vertical excitation energies and uorescence emission energies of coumarin 153 in about 40 solvents. 20 The observed results reveal that both vertical excitation energies and uorescence emission energies are associated with the polarity of simple non-aromatic aprotic solvents.…”
