Coumarin-derivative-based off-on catalytic chemodosimeter for Cu2+ ions

Chem Commun (Camb). 2009 Aug 28:(32):4838-40. doi: 10.1039/b908638b. Epub 2009 Jul 3.

Abstract

In this study, a new coumarin derivative is shown to be a highly effective turn-on fluorescent sensor that is catalytically hydrolyzed by Cu2+, and the catalytic process induces a large increase in the fluorescence intensity, due to amplification of the fluorescence signal.
