title: A new turn on coumarin-based fluorescence probe for Ga(3+) detection in aqueous solution.
abstract: The probe CT was synthesized and investigated as a novel label-free chemosensor for Ga(3+) detection in water. Probe CT showed remarkable selectivity and sensitivity for Ga(3+) in Tris-HCl aqueous buffer solution (pH7.0). The chemosensor responded rapidly to Ga(3+) with a 1:1 stoichiometry. Meanwhile, the unapparent changes of fluorescence lifetime decays suggest the turn-on process of probe CT by Ga(3+) which appears to be a static mechanism.
