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