title: A water-soluble 1,8-naphthalimide-based 'turn on' fluorescent chemosensor for selective and sensitive recognition of mercury ion in water.
abstract: A water-soluble 1,8-naphthalimide-based fluorescent chemosensor 1, bearing two acetic carboxylic moieties, exhibited high selectivity and sensitivity for recognition of Hg(2+) ion in water over other heavy and transition metal (HTM) ions with fluorescent enhancement. An increase in the fluorescent intensity at 562 nm was due to the formation of a 1:1 1-Hg(2+) inclusion complex.
