title: N-phenyl-1-naphthylamine/β-cyclodextrin inclusion complex as a new fluorescent probe for rapid and visual detection of Pd(2+).
abstract: Inclusion complex between N-phenyl-1-naphthylamine (NPN) and β-cyclodextrin (β-CD) was studied by FT-IR, (1)H and 2D NMR, XRD, FT-Raman, SEM and DSC techniques. The formation of 1:1 stoichiometric inclusion complex of NPN with β-CD was proposed based on the Nuclear magnetic resonance spectroscopy and Molecular docking study. The molecular encapsulation of host-guest inclusion complex based on simple chemosensor has high selectivity and sensitivity for the determination of Pd(2+) ion. Host-guest inclusion complex as a spectroscopic probe is used for the detection of transition metal cation Pd(2+). Coordination of this Pd(2+) with (NPN/β-CD) inclusion complex exhibited a noticeable color change in the solution state it used for naked-eye detection.
