以N，N '-双（5-间苯二甲酸）萘二甲酰亚胺（H4 L）为原料，构建了一种新型氢键有机骨架（HOF）FJU-200。FJU-200具有良好的苯胺和紫外检测双重功能。FJU-200是第一例具有视觉颜色变化和光致发光猝灭双重传感功能的霍夫检测苯胺，苯胺的检测限可达5.5 × 10 - 4 mol/L。FJU-200在紫外光下会迅速从浅黄色变为土褐色，这使得使用FJU-200实现分钟级紫外检测成为可能。另外，为了使用方便，还编制了FJU-200试卷。使用它们，可以实现方便、快速的苯胺或紫外检测。X射线单晶结构分析表明，与原始FJU-200相比，PhNH2@FJU-200和UV-FJU-200的孔径都增大了，骨架中H2 L2 −的二面角发生了变化。
A novel hydrogen-bonded organic frameworks (HOFs)FJU-200has been constructed fromN,N'-bis(5-isophthalic acid)naphthalimide (H4L).FJU-200has a good dual-function of aniline and ultraviolet detection.FJU-200is the first case of HOF with dual sensing of visual color changes and photoluminescence quenching for aniline detection, and the detection limit of aniline can reach 5.5 × 10−4mol/L. Under ultravioletFJU-200will rapidly change from light yellow to rustic brown, which makes it possible to useFJU-200to achieve minute-level ultraviolet detection. Moreover, for more convenient use,FJU-200test papers are prepared. Using them, convenient and fast aniline or ultraviolet detection can be realized. The single-crystal X-ray structures show that compared with the originalFJU-200, bothPhNH2@FJU-200andUV-FJU-200have larger pore sizes, and the dihedral angles of the H2L2−in framework has been changed.
