A novel organic gelator (PZ) has been synthesized by rationally connecting a pillar[5]arene moiety and a bis(hexadecyloxy)phenyl functionalized acylhydrazone moiety. PZ could self-assemble into a supramolecular polymer and form a stable organogel (OPZ) in cyclohexanol by multi-self-assembly driving forces such as C-Hπ, ππ, vdW and hydrogen bonding interactions. The organogel (OPZ) shows blue aggregation-induced emission (AIE). Interestingly, the organogel OPZ could sense iodide ions (I) in the gel-gel state with high selectivity and sensitivity. The detection limit of OPZ for I is 9.4 × 10 M, indicating high sensitivity to I. Furthermore, a thin film based on OPZ was prepared, which could be used as a smart material for the detection of I as well as a fluorescent security display material.
一种新型的有机凝胶剂（PZ）通过合理连接[5]轮烯部分和双（十六烷氧基）苯基功能化酰腙部分合成。PZ 可以通过 C-Hπ、ππ、vdW 和氢键相互作用等多种自组装驱动力自组装成超分子聚合物，并在环己醇中形成稳定的有机凝胶（OPZ）。该有机凝胶（OPZ）表现出蓝相聚集诱导发射（AIE）。有趣的是，OPZ 有机凝胶在凝胶-凝胶状态下对碘离子（I）具有高选择性和灵敏度。OPZ 对 I 的检测限为 9.4×10-5 M，表明对 I 具有很高的灵敏度。此外，还制备了基于 OPZ 的薄膜，其可用作检测 I 的智能材料以及荧光安全显示材料。
