西北民族大学林奇团队报道了新型易合成联氨多通道检测吸附材料。相关研究成果发表在2024年11月26日出版的《中国化学》。

水合肼（DH）是一种应用广泛的化学试剂，但毒性很高。因此，开发低成本、易制备的DH检测和吸附材料具有重要意义。

该文设计并合成了一种基于双喹啉官能化萘二亚胺（DQ8）的新型且易于制备的超分子智能材料。在DQ8中，喹啉和萘二亚胺基团之间的协同作用被用来提高DH结合的选择性和敏感性。DQ8基晶体多孔材料（DQ8-CPM）可以同时检测和吸附DH，并在吸附DH蒸气后产生明显的荧光颜色变化。

更重要的是，DQ8-CPM在DH检测和吸附方面表现出良好的回收性能。同时，基于DQ8（DQ8-G）的智能凝胶通过颜色、荧光和状态变化对DH显示出多通道响应。DQ8对DH显示出高选择性和敏感性。DQ8对DH的检测限为8.6×10^-7mol/L。

根据对DH结合和反应机制的研究，喹啉和萘二亚胺基团之间的协同作用在DH反应过程中起着重要作用。通过协同效应开发DH检测和吸附材料是一种简单可行的方法。

Abstract: Hydrazine hydrate (DH) is a widely used chemical agent, but it is highly toxic. Thus, the development of low-cost and easy-to-prepare materials for the detection and adsorption of DH is very significant. Herein, a novel and easy-to-prepare supramolecular smart material based on bisquinoline-functionalized naphthalene diimide (DQ8) has been designed and synthesized. In the DQ8, the synergistic effect between quinoline and naphthalene diimide groups has been employed to improve the selectivity and sensitivity for binding of DH. The DQ8-based crystalline porous material (DQ8-CPM) can simultaneously detect and adsorb DH and produce noticeable fluorescence color changes after adsorption of DH vapor. More significantly, the DQ8-CPM shows nice recycling performance on DH detection and adsorption. Meanwhile, a smart gel based on DQ8 (DQ8-G) shows multi-channel response for DH through color, fluorescence, and state changes. The DQ8 shows high selectivity and sensitivity for DH. The detection limit of DQ8 for DH is 8.6 ×10–7 mol/L. According to the investigation of the DH binding and response mechanism, the synergistic effect between quinoline and naphthalene diimide groups plays an important role in the DH response process. It's a simple and feasible way to develop materials for detection and adsorption of DH through synergistic effects.
