A “three-components” supramolecular assembly has been fabricated by mixing 2, 2’: 6’, 2”-terpyridine attached pillar[5]arene, cyano and triazole bearing alkyl chain and Zn²⁺ in solvent of CHCl₃ and CH₃CN. The driving forces for the assembly were believed to be host-guest and metal chelating interactions as characterized by ¹H NMR, UV-vis and fluorescence spectra. The supramolecular organo-gel formed upon the concentration of components amount to 1 M. The supramolecular displayed nitrobenzene based explosive sensing capability using picric acid, ortho-nitrobenzene and phenol as samples. The assembly was most sensitive towards picric acid among the three analytes. The limit of detection for picric acid was determined to be 1.66 × 10⁻⁴ M.

Pillar[5]芳烃基“三组分”超分子组装与硝基苯基爆炸荧光传感性能

通过在CHCl ₃和CH ₃溶剂中混合2, 2': 6', 2”-三联吡啶连接的柱[5]芳烃、带有烷基链的氰基和三唑以及Zn ²⁺制备了“三组分”超分子组装体CN. 组装的驱动力被认为是主客体和金属螯合相互作用，如¹ H NMR、UV-vis 和荧光光谱所表征。组分浓度达到 1 M 后形成的超分子有机凝胶。使用苦味酸、邻位-硝基苯和苯酚作为样品。在三种分析物中，该组件对苦味酸最敏感。苦味酸的检测限确定为 1.66 × 10 ^-4 M。
