The structure of the sensor was characterized by IR, 1H NMR and MS. We introduced nitrogen and oxygen heteroatoms as chelating sites and ethyl-7-hydroxycoumarin-3-carboxylate group was introduced as fluorophore to achieve recognitions. HF-1 displayed high selectivity and sensitivity for iron ion in a very short time, which served as an ON–OFF type sensor. HF-1 were designed with ease of synthesis and low cost. Therefore, the sensor have potential applications in physiological and environmental systems for iron ion detection. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
