A colorimetric chemosensor TBS-NA, 4-(tert-butyldimethylsilyloxy)-N-butyl-naphthalimide was designed and synthesized. Addition of fluoride ion to a CH 3 CN solution of TBS-NA can result in an obvious color change (from colorless to yellow) and UV–Vis absorption spectral change in a short time. This indicated that TBS-NA had highly selectivity for fluoride detection over other anions, such...
