Journal ArticleDOI
Flavonols and Crown-Flavonols as Metal Cation Chelators. The Different Nature of Ba2+and Mg2+Complexes
Alexander D. Roshal,and A. V. Grigorovich,Andrey O. Doroshenko,Vasyl G. Pivovarenko,Alexander P. Demchenko +4 more
TL;DR: In this paper, it was shown that 3-hydroxyflavone derivatives exhibit excited-state intramolecular proton transfer (ESIPT) reaction with significant (60−80 nm) shifts of fluorescence spectra between normal and phototautomer forms.
Journal ArticleDOI
Excited state intramolecular proton transfer reaction and luminescent properties of theortho-hydroxy derivatives of 2,5-diphenyl-1,3,4-oxadiazole
TL;DR: In this paper, the rate constants for the excited state intramolecular proton transfer (ESIPT) reaction and radiationless degradation of the energy of electronic excitation in the phototautomer form, were made on the basis of fluorescence quantum yields and fluorescence kinetic measurements.
Journal ArticleDOI
Flavonols as metal-ion chelators : Complex formation with Mg2+ and Ba2+ cations in the excited state
Alexander D. Roshal,A.V. Grigorovich,Andrey O. Doroshenko,Vasyl G. Pivovarenko,Alexander P. Demchenko +4 more
TL;DR: In this paper, the excited state complexation of flavonol derivatives with alkali and alkali-earth metal ions was investigated, and it was found that chelating magnesium complexes are more stable than in the ground state.
Journal ArticleDOI
Synthesis of water-soluble, ring-substituted squaraine dyes and their evaluation as fluorescent probes and labels
Anatoliy L. Tatarets,Irina A. Fedyunyayeva,Tatyana S. Dyubko,Yevgeniy A. Povrozin,Andrey O. Doroshenko,Ewald A. Terpetschnig,Leonid D. Patsenker,Leonid D. Patsenker +7 more
TL;DR: A series of ring-substituted squaraines absorbing and emitting in the red and NIR spectral region was synthesized and their spectral and photophysical properties were measured and compared to Cy5, a commonly used fluorescent label.
Journal ArticleDOI
Ionic Equilibria of Fluorophores in Organized Solutions: The Influence of Micellar Microenvironment on Protolytic and Photophysical Properties of Rhodamine B
TL;DR: Ionic equilibria and fluorescence decay of rhodamine B were studied in micellar solutions of SDS with various additives (NaCl, pentanol-1, crown ether, and tetra-n-butyl ammonium salt), as well as in β-cyclodextrin solutions as discussed by the authors.
