A colorimetric and fluorescent chemosensor (L) for Al(III) was synthesized and fully characterized. L could be both used as a colorimetric and fluorescent chemosensor for the detection of Al(3+) ions with low detection limit (8.87×10(-7) M) in CH3CN-H2O (1:1, v/v) solution. The binding ratio of L-Al(3+) was determined from the Job plot (absorption and fluorescence spectra) and MALDI-TOF MS data to be 1:1. The binding constant (Ka) of Al(3+) binding to L was calculated to be 4.8×10(5) M(-1) from a Benesi-Hildebrand plot. Moreover, the binding site of L with Al(3+) was determined by (1)H NMR titration experiment.
合成了一种用于铝（III）的比色和荧光化学传感器（L）并对其进行了全面表征。L 可用作比色和荧光化学传感器，用于在乙腈 - 水（1:1，v/v）溶液中检测铝（3 +）离子，检测限低（8.87×10（-7）M）。通过 Job 曲线（吸收和荧光光谱）和基质辅助激光解吸电离飞行时间质谱（MALDI - TOF MS）数据确定 L - 铝（3 +） 的结合比为 1:1。根据 Benesi - Hildebrand 曲线计算出铝（3 +）与 L 的结合常数（Ka）为 4.8×10（5）M（-1）。此外，通过核磁共振氢谱（1）H NMR 滴定实验确定了 L 与铝（3 +）的结合位点。
