摘要：

A bifunctional Schiff base fluorescent sensor 2 (receptor 2) was prepared and its metal ions and anions sensing properties were investigated. Receptor 2 exhibited an excellent selective fluorescence response toward Al3+ and colorimetric response (from yellow to colorless) toward CN-, respectively among a series of ions. Moreover, the detection limits of receptor 2 for Al3+ and CN- were determined to be 14 nM and 73 nM, respectively. The two detection limit values were sufficiently low to detect nano-molar concenration of Al3+ and CN. (C) 2015 Elsevier B.V. All rights reserved.
