A BODIPY-based dual-responsive turn-on fluorescent probe for NO and nitrite

A o-phenylenediamine-BODIPY-based dual-response turn-on low-background fluorescence probe 1 for sensitive and selective detection of NO and nitrite has been successfully developed. The resulted 8-benzotriazolyl BODIPY could recognize bithiol such as Cys, Hcy, and GSH.177
