合成了铝(III)的比色荧光化学传感器(L)，并对其进行了表征。在CH3CN-H2O(1：1，v/v)溶液中，L可作为比色和荧光化学传感器用于Al~(3+)离子的检测，检测下限为8.87×10~(-7)M。根据JOB图(吸收光谱和荧光光谱)和MALDI-TOF MS数据确定了L与铝离子的结合比为1：1。用贝内西-希尔德布兰德曲线计算了L与铝离子的结合常数(K-a)为4.8×10(5)M-1。通过H-1NMR滴定实验确定了L与Al~(3+)的结合位置。(C)2015爱思唯尔B.V.保留所有权利。
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 Al3+ ions with low detection limit (8.87 x 10(-7) M) in CH3CN-H2O (1:1, v/v) solution. The binding ratio of L-Al3+ was determined from the Job plot (absorption and fluorescence spectra) and MALDI-TOF MS data to be 1:1. The binding constant (K-a) of Al3+ binding to L was calculated to be 4.8 x 10(5) M-1 from a Benesi-Hildebrand plot. Moreover, the binding site of L with Al3+ was determined by H-1 NMR titration experiment. (C) 2015 Elsevier B.V. All rights reserved.
