A near-infrared fluorescence chemodosimeter for fluoride via specific Si-O cleavage
چکیده انگلیسی

A near-infrared (NIR) fluorescent chemodosimeter for F− was developed on the basis of dicyanomethylene-4H-chromene derivative, with several merits such as a high off/on ratio response, NIR fluorescence, and high selectivity to F−. The F− triggered specific Si-O cleavage of DCPOSi to release DCPO− is responsible for the dramatic color change and distinct NIR fluorescence enhancement at 718 nm.

A chemodosimeter shows F−-selective fluorescent response via the specific Si-O cleavage with F−, displaying a dramatic color change and distinct NIR fluorescence enhancement at 718 nm.
