A novel tripodal organic gelator (JP5) decorated with three pillar[5]arene tails was designed, synthesized and thoroughly characterized. The stable supramolecular polymer JP5G was obtained within 0.5 minutes by the self-assembly of gelator JP5 in cyclohexanol via C–H⋯π, π⋯π stacking, vdW forces and hydrogen bonding interactions. Interestingly, the supramolecular polymer JP5G showed strong aggregation-induced emission (AIE) and could respond to multiple external stimuli. Simultaneously, JP5G presented special selectivity and high sensitivity for Hg²⁺; the fluorescence detection limit of JP5G for Hg²⁺ is 1.02 × 10⁻⁸ M. In addition, the JP5G xerogel could effectively remove Hg²⁺ from water. What's more, a thin film based on the supramolecular polymer (JP5G) was prepared that could act as a convenient test kit for the detection of Hg²⁺. The use of tri-pillar[5]arene to construct a tripodal pillar[5]arene-based organic gelator constitutes a novel and efficient method for the design and synthesis of novel functional supramolecular polymers.

基于三柱[5]芳烃的多刺激响应超分子聚合物，用于荧光检测和分离Hg 2 ⁺†

设计，合成并彻底表征了新型的装饰有三根[5]芳烃尾部的三脚架有机胶凝剂（JP5）。稳定的超分子聚合物JP5G是在0.5分钟内通过C–H⋯π，π⋯π堆积，vdW力和氢键相互作用通过在环己醇中自组装的JP5胶凝剂而获得的。有趣的是，超分子聚合物JP5G表现出强的聚集诱导发射（AIE），并且可以响应多种外部刺激。同时，JP5G对Hg ²⁺具有特殊的选择性和高灵敏度。Hg ²⁺对JP5G的荧光检测极限为1.02×10 ^-8 M.另外，JP5G干凝胶可以有效地除去汞²⁺从水中。此外，制备了基于超分子聚合物（JP5G）的薄膜，该薄膜可以用作检测Hg ²⁺的便捷测试试剂盒。使用三支柱[5]芳烃构建三脚架支柱[5]芳烃基有机胶凝剂，构成了一种新颖而有效的方法，用于设计和合成新型功能性超分子聚合物。
