A HKOCl-2 series of new fluorescent probes for hypochlorous acid (HOCl) detection in live cells is reported. The probes exhibit excellent selectivity, sensitivity, and chemostability toward HOCl. In particular, HKOCl-2b rapidly and selectively detects endogenous HOCl in both human and mouse macrophages. These probes could therefore serve as promising discovery tools to help elucidate biological functions of HOCl.
