A novel Al3+ chemosensor NPA was designed and synthesized on basis of the mechanism of ICT and CHEF. Upon addition of Al3+, the probe NPA displayed a bright green fluorescence under UV radiation and visual color change from yellow to colorless. Spectrum titrations showed that NPA could be recognized as a fluorescent turn-on probe with 10−8 M detection level. The probe was successfully applied in real water sample and test paper. More important, NPA-Al3+ complex were used as a fluorescent turn-off probe for the detection of ClO− with the detection as low as 2.34 × 10−8 M. The performance of NPA to Al3+ and NPA-Al3+ complex to ClO− demonstrated that NPA could be served as a sensitive probe and exhibit INHIBIT logic gate behavior with Al3+ and ClO− as inputs. |
