A new indole‐based compound N‐(pyridine‐2‐ylmethyl)‐1H‐indole‐2‐carboxamide (FL) which could selectively recognize Al3+ had been designed, synthesized and evaluated. FL could detect Al3+ with high sensitivity. The fluorescence intensity of FL‐Al3+ solution was linear dependence to the concentration of Al3+ in the ranges from 0 to 5 μmol/L. The addition of Al3+ caused quenching of fluorescence intensity and the limit of detection for Al3+ was as low as 1.79×10−9 M. The binding ratio of FL‐Al3+ was obtained 3:2 by Job's plot and the binding constant was 9.37×105. Moreover, FL had been successfully applied in real sample detection.
