Three-level reversible fluorescence switching of donor–acceptor type bipyridine molecules by simple protonation–deprotonation equilibria is discussed with detailed analysis of the relevant steps. Site-specific protonation causes structural changes in absorbing and emitting species and their ratio, which leads to dramatic change in fluorescence.
