Two kinds of modified coumarin derivatives with another intramolecular conjugated charge transfer moiety have been synthesized in this work. The photophysical behavior of these compounds in solvents with different polarity and viscosity were studied. Much low and wide span of spectral range of these compounds are due to the existence of the flexible non-symmetrical stilbene structure and low intramolecular charge transfer ability.

Key words: Coumarin, Fluorescent probe, Intramolecular charge transfer
