Abstract:
Herein, instant and precise control of fluorescent emission color and transmittance could be carried out by ultrasound-promoted gel-to-gel transition of naphthalimide derivatives containing CN unit. It is proved that ultrasound triggered an irreversible and efficient configuration transformation of N1 from "trans to cis" form in gel state, which is stabilized by intermolecular hydrogen bonding interaction and not observed in the solution state.
