Abstract: (i) O-phenolnaphthylimine (PNI) was synthesized by the condensation reaction of 2-hydroxynaphthalene-1-carbaldehyde and 2-aminophenol in ethanol with 90% yield.
(ii) The structural elucidation of the compound was done by using IR, 1H NMR, 13C NMR, and Mass spectral techniques.
(iii) The chemosensory ability of β-CD: PNI inclusion complex was investigated thoroughly for various metal cations and we found the emission of the complex showed a linear increase in the intensity for Al3+ with the linearity range of 20 µM to 300 µM For selectivity and Sensitivity analysis of β-CD: PNI inclusion complex with Al3+, Competitive experiment was carried out and it shows good sensing with Al3+ with the limit of detection of 44.9 µM and limit of quantification of 136 µM.
Summary: In summary, we developed a new Schiff base compound o-Phenolnaphthylimine (PNI) and it was characterized and confirmed by FT-IR, 1H NMR, 13C NMR and Mass spectral techniques. The β-CD: PNI complex shows good sensing towards Al3+ ion, using fluorescence spectroscopy.
