title: Proton-induced fluorescence switching in novel naphthalimide-dansylamide dyads.
abstract: [reaction: see text] Three novel bichromophoric dyads containing dansylamide and 1,8-naphthalimide linked by oligomethylene spacers of varying length were prepared. The fluorescent moiety can be reversibly selected by protonation/deprotonation of the dansyl residue via control of singlet-singlet energy transfer and photoinduced electron transfer, leading to a molecular optical switch with two spectrally distinguished "on" states.
