Abstract We have synthesizedN-methyl-9-anthrylhydroxamic acid, which is a fluorescent analogue ofN-methylbenzohydroxamic acid. Complexation with various di- and trivalent metal ions occurs (logK from 4 to 5) in water with resulting fluorescence quenching. Because the Fe(III) and Al(III) complexes substituted rather slowly, the addition of EDTA provides a temporal method for obtaining some selectivity in the chemosensor.
