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.
采用傅里叶变换红外光谱（FT-IR）、核磁共振氢谱（¹H NMR）、二维核磁共振谱（2D NMR）、X射线衍射（XRD）、傅里叶变换拉曼光谱（FT-Raman）、扫描电子显微镜（SEM）和差示扫描量热法（DSC）等技术研究了N-苯基-1-萘胺（NPN）与β-环糊精（β-CD）之间的包合物。基于核磁共振光谱和分子对接研究，提出了NPN与β-CD形成化学计量比为1:1的包合物。基于简单化学传感器的主客体包合物的分子封装对钯离子（Pd²⁺）的测定具有高选择性和高灵敏度。主客体包合物作为光谱探针用于检测过渡金属阳离子Pd²⁺。这种Pd²⁺与（NPN/β-CD）包合物的配位在溶液状态下表现出明显的颜色变化，可用于肉眼检测。
