Synthesis of novel push-pull fluorescent dyes – 7-(diethylamino)furo[3,2-c]coumarin and 7-(diethylamino)thieno[3,2-c]coumarin derivatives

[摘要] Novel push-pull fluorescent dyes, 7-(diethylamino)furo[3,2- c ]coumarin and 7-(diethylamino)thieno[3,2- c ]coumarin derivatives, were designed and synthesized using formyl derivatives of furo- and thieno[3,2- c ]coumarins as key intermediates. Electron absorption and emission spectra of the dyes were recorded in different solvents. The longest-wave bands in the electron absorption spectra of the dyes are suggested to be of push-pull nature.
