摘要：

Two novel chemosensors (2a and 2b) were synthesized by facile condensation of the binding unit (l-histidine) and the fluorophores (anthracene and dansyl groups). Both of them displayed high selectivity and sensitivity towards Fe3+ over other metal ions in aqueous solution. (3+) that would lead to fluorescence quenching of the fluorophores when Fe3+ was bound to the recognition units. l-histidine was a good coordination motif for Fe3+ and both the anthracene and dansyl groups can sensitively report the sensing information.
