Abstract

A new 1,8-naphthalimide derivative bearing an aza-15-crown-5 macrocycle (1) has been synthesized as a chemosensor for Hg 2+ by a two-step reaction. The sensor shows selectivity to Hg 2+ over 11 other metal cations in aqueous media. Upon addition of Hg 2+, the fluorescence emission of the sensor at 537 nm is significantly quenched along with 22 nm blue-shift that makes this compound a useful sensor for Hg 2+ measurement.
