Simple 1,8-diaminonaphthalene-based fluorescence chemosensor for hypochlorites and its practical application

In this work, we have successfully provided a novel strategy for employing commercially available fluorescent reagent as probe for hypochlorite. The strategy is based on a specific reaction promoted by hypochlorite: namely, hypochlorite oxidizes aminos of probe to imines, which has not yet been used in the fluorescent hypochlorite probe design. Interestingly, the probe showed a fluorescent response to hypochlorite with the emission shift from blue to green. Furthermore, the probe displayed high selectivity for hypochlorite over other species. The probe can be used in detecting practical sample and bioimagings. The probe developed herein made it become possible that organic complexes containing amino can be used to design fluorescence probes for hypochlorite. (C) 2014 Elsevier B.V. All rights reserved.
