Autor: M. N. Khimich, N. I. Makarova, M. I. Knyazhansky, B. M. Uzhinov

Publikováno v: International Journal of Photoenergy, Vol 6, Iss 2, Pp 69-72 (2004)

The fluorescence spectrum of N-(1-anthryl)-2,4,6-trimethylpyridinium cation (1) has an anomalously high Stokes' shift. The fluorescence spectra of 1 in ethanol and butyronitrile are shifted to shortwavelength region and fluorescence quantum yield inc

Influence of the configuration of the amine nitrogen atom on the efficiency of fluorescence of 4-aminonaphthalimide derivatives

Autor: Yu. A. Mednykh, Valery V. Volchkov, Yu. A. Manaev, B. M. Uzhinov

Publikováno v: Russian Journal of General Chemistry. 74:1728-1733

The fluorescence properties of 4-aminonaphthalimide were studied in relation to the size of the heterocycle incorporating the amine nitrogen atom, the temperature, and the polarity of the medium. Increases in the temperature, polarity of the medium,
