title: Chromogenic and fluorescent 'turn-on' chemodosimeter for fluoride based on a F(-)-triggered cascade reaction.
abstract: We developed a new chromogenic and fluorescent 'turn-on' chemodosimeter 1 based on a F(-)-triggered cascade reaction. This system displayed significant changes in UV/vis absorption and fluorescence emission intensities selectively for F(-) over other anions in a mixture of CH3CN/H2O(95 : 5, v/v) and in acetonitrile.
