Аннотация:Novel push-pull fluorescent dyes – 7-(diethylamino)furo- and 7-(diethylamino)thieno[3,2-c]coumarins derivatives have been designed and synthesized using formyl derivatives of furo- and thieno[3,2-c]coumarins as starting materials. Electron absorption spectra of the dyes have been recorded in different solvents. Effects of dyes structure and solvent on their spectral characteristics were analyzed. The longest-wave electron transitions in the studied compounds were computationally shown to be of push-pull nature.
