title = "Water-soluble fluorescent chemosensors: in tune with protons",
abstract = "Development of fluorescent chemosensors able to bind and signal either cations or anions in aqueous media is reviewed. Abundant examples in the literature support the versatility of polyamine-based chemosensors towards applications in water. The chemosensors described have a common structure consisting of a binding polyamine motif linked to a fluorophoric unit. Different sensing mechanisms are explored: photoinduced electron transfer from the amine lone pairs to the fluorophoric unit(s), photoinduced electron transfer between fluorophoric units, energy transfer, excimer and exciplex formation. The protonation equilibria of the polyamine chains render great versatility to the chemosensors since they are at the basis of the different sensing mechanisms and also allows the tuning between cation and anion binding regime.",
