ABSTRACT=In recent years, the widely application of fluoride materials have grown rapidly, thereupon the excess discharge in surrounding environment, especially in the drinking water and organic effluent, became the potential hazard to the human being, even resulted in fluorosis disease. The development of the high effective and convenient method to recognize fluoride anion in surrounding environments seems necessary and urgent. Among which, the colorimetric and fluorescence fluoride chemosensor with obviously color changing allowing the naked eye detection with high sensitivity and selectivity are more interesting and challenging. In this minireview, the current novel colorimetric and fluorescence chemosensors for fluoride anions by hydrogen-bond interaction are introduced, including of obviously color changing by naked eye detection, high sensitivity and selectivity, non-pollution and fluoride extraction ability, aqueous detection and other additional functions. Finally, the perspective of the fluoride chemosensor design concept and potential evolution trends are pointed out.
