A simple Schiff base (L) based on 2-hydroxyacetophenone and o-phenylenediamine was prepared which acts as an effective fluorescent sensor for Al with ca. 9.0 fold enhancement in fluorescence intensity and detection limit 10 M. L can quite clearly distinguish Al over other metal ions Zn, Hg, Cd, Pb, Mn, Mg, Co, Ni, Cu, Ca, K, Li, Na and Fe. Cyclic voltammogram and square wave voltammogram of L shows a significant change on interaction with Al. Spectroscopic data and DFT calculations confirm 1:1 interaction between L and Al which is reversible with respect to NaEDTA.
制备了一种基于2-羟基苯乙酮和邻苯二胺的简单席夫碱（L），它可作为铝的有效荧光传感器，荧光强度增强约9.0倍，检测限为10 M。L能非常清晰地将铝与其他金属离子锌、汞、镉、铅、锰、镁、钴、镍、铜、钙、钾、锂、钠和铁区分开来。L的循环伏安图和方波伏安图显示与铝相互作用时有显著变化。光谱数据和密度泛函理论计算证实L与铝之间存在1:1相互作用，相对于乙二胺四乙酸二钠是可逆的。
