Dependence of Fluorescence Properties of Compounds from Psoralen, Angelicin, and Carbazole Series on the Character of Their Terminal Substituents
摘要:
Absorption, luminescence excitation and emission spectra of nine compounds from 4,8,4'-tri-methylpsoralen, 4,4'-dimethylangelicin, and 1,2,3,4-tetrahydrocarbazole series with various terminal substituents were studied in water and 2-propanol. Proceeding from the data obtained in the present and also some previous studies we have formulated the main rules concerning a general mechanism of changes in the fluorescence characteristics of DNA-specific dyes depending on their chemical structure, substrate properties, and measurement medium.
