[摘要]：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. (C) 2011 Elsevier Ltd. All rights reserved. |
