Based on a through bond energy transfer (TBET) between Rhodamine and a naphthalimide fluorophore, a fluorescent ratiometric chemodosimeter RN1 was designed and prepared for single selective detection of Cu2+ in aqueous solution and in living cells, as Cu2+ acts as not only a selective recognizing guest but also a hydrolytic promoter.
