摘要：

A new pyrene derivative BF bearing a furan group was synthesized via a one-step reaction as a colorimetric and ratiometric chemosensor for Al3+in ethanol-H2O(9:1,v/v,pH 7.2,HEPES buffer)solution.This chemosensor could selectively recognize Al3+in the presence of other competing ions.Low limit of detection(LOD) and high association constant revealed its superior sensitivity and binding affinity toward Al3+.Besides,the probe BF performed perfectly in a reversibility test using EDTA.The mechanism of the interaction has been confirmed by1H NMR titration.Importantly,chemosensor BF has also been utilized to detect Al3+on test paper strips,which showed its potential for practical applications.
