Stimuli-response supramolecular fluorescent materials have received significant attention in recent years since they endow specific and unique properties to materials. Herein, a bi-acylhydrazone supramolecular gelator HT was successfully prepared by simple Schiff base reaction. Interestingly, the gelator HT could self-assemble into supramolecular gel HT-G in DMSO-H₂O binary solutions via π-π stacking interactions. Simultaneously, gel HT-G showed specially selective and ultrasensitive sensing property for CN⁻. The limit of lowest detection of the gel for CN⁻ is 0.50 nM. In addition, the thin films based on the HT-G and HT-G + CN⁻ were also prepared, which could not only act as supramolecular fluorescent material but a convenient and efficient tool for detection CN⁻.

近年来，由于刺激响应性超分子荧光材料赋予材料独特和独特的性能，因此受到了极大的关注。在此，通过简单的席夫碱反应成功地制备了双酰基hydr超分子凝胶剂HT。有趣的是，胶凝剂HT可以通过π-π堆积相互作用在DMSO-H ₂ O二元溶液中自组装成超分子凝胶HT-G。同时，凝胶HT-G显示出特别的选择性和超灵敏检测属性CN ^- 。最低的检测凝胶为CN的极限^-是0.50纳米。此外，基于HT-G和HT-G + CN ^-还制备，这可能不仅充当超分子荧光材料，但是用于检测CN一个方便和有效的工具^- 。
