Chemosensor for detecting fluoride ion and method for preparing the same

摘要

The present invention relates to a chemical sensor for detecting fluorine ions exhibiting high selectivity and sensitivity and a method for producing the same. More specifically, the present invention relates to a chemical sensor for detecting fluorine ions, To a chemical sensor for fluorine ion detection. The chemical sensor for fluorine ion detection of the present invention comprises silylating the surface of silica nanoparticles with trimethoxysilane having an amino group; Immobilizing fluorescein isothiocyanate on the silylated nanoparticles; And silylating the phenol group of the fluorescein isothiocyanate with tert-butyldimethylsilyl chloride, exhibiting high selectivity and sensitivity in fluorescence " turn-on " upon reaction with fluorine ions , By changing the type of amino molecule silylating the silica nanoparticles and the loading amount of fluorescein isothiocyanate, it can be transformed into a chemical sensor suitable for various sensing ranges.
