As an important reactive nitrogen species, peroxynitrite (ONOO) is closely related to the occurrence of various diseases. The development of methods to detect ONOO is of great significance for understanding its related physiological and pathological mechanisms. A novel ONOO fluorescent probe TPE-ONOO was successfully constructed using tetraphenylethylene as a fluorophore and a pyrylium group as the specific recognition site of ONOO. The probe showed high selectivity, strong anti-interference ability and high sensitivity to ONOO. Cell assays suggested that the probe had low cytotoxicity and was successfully used for imaging monitoring of exogenous and endogenous ONOO in cells. The novel probe synthesized here provides an efficient tool for studying ONOOphysiological processes.
