Inclusion complex between N-phenyl-1-naphthylamine (NPN) and beta-cyclodextrin (beta-CD) was studied by FT-IR, H-1 and 2D NMR, XRD, FT-Raman, SEM and DSC techniques. The formation of 1:1 stoichiometric inclusion complex of NPN with beta-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 Pd2+ ion. Host-guest inclusion complex as a spectroscopic probe is used for the detection of transition metal cation Pd2+. Coordination of this Pd2+ with (NPN/beta-CD) inclusion complex exhibited a noticeable color change in the solution state it used for naked-eye detection.
