30 May 2002 Red-edge excitation effect in intramolecular proton transfer in flavonols
Author Affiliations +
To investigate of 4'-diethylamino (FET) and 4'-(15-azacrown- 5) (FCR) derivatives of 3-hydroxyflavone in binary solvents and erythrocyte ghosts, we used the red-edge excitation spectroscopy. The results obtained prove the existence of spectral heterogeneity of flavonols in the studied systems. The effect manifests itself in the dependence of the efficiency of excited-state intramolecular proton transfer on the excitation frequency.
