| Abstract: A novel fluorescent sensor 1,5-diphenyl-3-(10-(morpholinemethyl)anthracene-2-yl)pyrazoline (PMAP) was synthesized successfully, and characterized by 1H NMR and 13C NMR spectracopy and X ray single crystal diffraction. Selective recognition of PMAP for cations was investigated by fluorescence emission spectrum and ultraviolet-visible absorption spectrum.The results showed that the PMAP exhibited high selective and sensitive to Fe3+ (for a ca. 45 nm red shift) and Cu2+, showing color change from pale yellow to blue and the fluorescence quantum yield decreased from 0.14 to 0.05 and 0.04, respectively. The sensor demonstrated a 1:1 binding stoichiometry to Fe3+/Cu2+ as well as a low detection limit of ca. 1 μmol·L-1, and interference experiments revealed that this sensor had an excellent anti-interference ability. Furthermore, the sensor can be effectively applied for the detection of Cu2+ and Fe3+ in practical water samples. In addition, a three-input NOR logic gate circuit was constructed at the molecular level by the quantum yield of PMAP for Fe3+, Cu2+and H+ in different combinations. |
