本文设计、合成并评价了一种简单的基于腙的“开启”荧光化学传感器。在加入Al3+离子后，传感器在490 nm处表现出高选择性和高灵敏度，增强了900倍，这是由于光诱导电子转移（PET）和螯合增强荧光（CHEF）。该传感器对Al3+的检出限可达10(-7)mol/L。(C) 2015 Elsevier B.V.版权所有
In this article, a simple hydrazone-based "turn on" fluorescent chemosensor has been designed, synthesized and evaluated. Upon addition of Al3+ ions, the sensor showed high selectivity and sensitivity with a 900-fold enhancement at 490 nm, which was attributed to the photoinduced electron-transfer (PET) and the chelation-enhanced fluorescence (CHEF). In addition, the detection limit of this sensor for Al3+ could reach 10(-7) mol/L. (C) 2015 Elsevier B.V. All rights reserved.
