eng	3-Aminobenzanthrone Derivatives Exhibiting Intermolecular Exciplex Formation	N-Acetyl-3-aminobenzanthrone derivatives containing a tertiary amino group on acetyl CH2 group show dual fluorescene. Both emission bands originate from the same molecule. Time resolved measurements indicate that the red emission corresponds to an intramolecular exciplex state. The formation of this state is the dominant proces quenching the green fluorescence of the system in relaxed Frank-Condon state.	3-Aminobenzanthrone derivatives, Intramolecular exciplex formation, UV/Vis absorption and fluorescence spectra, Dual fluorescence, Solvent effect on formation of exciplexes, Time resolved measurements.
