中文摘要：

设计并合成了基于4-氨基吖啶酮和吲哚的小分子荧光探针4-（（（1H-吲哚-3）苄基）氨基）吖啶-9（10H）-酮（AAY）,结构经过氢谱和碳谱确认。通过实验和理论模拟研究了该化合物的性能,结果表明,在水的缓冲溶液中（pH 2.2-12.2）,AAY能够专一识别Co^2＋,具有较强的抗干扰能力,AAY与Co^2＋的配位比为1：1,检出限为29.1 nmol/L。

英文摘要：

Based on our previous studies,the small molecular fluorescent probe 4-（（（ 1H-indol-3-yl）methylene） amino） acridin-9（ 10H）-one（ AAY） was further designed and synthesized. The structure was confirmed by 1^ H NMR and 13^ C NMR. The properties of AAY were studies through a series of experiments and theoretical modeling. The results showed that the AAY could selectively recognize Co-^2＋in aqueous solution（ pH 2. 2-12. 2） with stronger anti-interference ability. The coordination ratio is 1： 1. The detection limit was 1. 8 nmol/L.
