Abstract: Seven novel fluorescent coumarin derivatives were synthesized from 7-diethylamino-4-chloro
-3-formyl coumarin. The spectra of absorption, excitation and emission were dependent not
only on the structures and also on the concentration of dyes. The PPP-MO predictions can
only be consistent with the spectra in dilute solutions.

Key words: fluorescent, coumarin, synthesis
