S. Nishizawa et al., ANION SENSING BY A DONOR-SPACER-ACCEPTOR SYSTEM - AN INTRAMOLECULAR EXCIPLEX EMISSION ENHANCED BY HYDROGEN BOND-MEDIATED COMPLEXATION, Journal of the Chemical Society. Perkin transactions. II (Print), (11), 1998, pp. 2325-2327
A new donor-spacer-acceptor system, 1 shows monomer emission quenching
followed by intramolecular exciplex emission upon hydrogen bond-media
ted complexation of anions.
