A new Aluminum metal-organic frameworks(Al-MOF) based on tricarboxylate ligands(L){L=2,2’,2’-([1,3,5]-triazine-2,4,6-triimino)tribenzoic acid)} has been designed and synthesized. It can be served as a platform of multi-responsive fluorescence sensor for Fe³⁺, Sr²⁺ and SiO₃²⁻ in water, which is mainly due to the significant enhancement effect of these ions on the fluorescence intensity of Al-MOF. Especially, Fe³⁺ ions are rarely able to induce MOFs fluorescence enhancement. The limit of detection for three kinds of ions is 6.62*10⁻⁶ M, 5.37*10⁻⁶ M, 6.85*10⁻¹⁰ M respectively. Meanwhile, It can also be used as a multi-response fluorescence probe to detect toluene in DMF solution, limit of detection is 9.16*10⁻³ M respectively. The structure of Al-MOF was characterized by FTIR, ¹H NMR, SEM, TAG, PXRD and element analysis. The PXRD showed that the structure of Al-MOF remained the high water stability and pH stability. The application of water samples and vegetables showed that Al-MOF had high sensitive detection for Fe³⁺ ions.

基于三羧酸配体(L){L=2,2',2'-([1,3,5]-triazine-2,4,6-triimino)tribenzoic的新型铝金属有机骨架(Al-MOF)酸)} 已被设计和合成。它可以作为水中Fe ³⁺、Sr ²⁺和SiO ₃ ^2-的多响应荧光传感器平台，这主要是由于这些离子对Al-MOF的荧光强度有显着的增强作用。特别是，Fe ³⁺离子很少能够诱导MOFs 荧光增强。三种离子的检测限为6.62*10 ^-6 M、5.37*10 ^-6 M、6.85*10 ^-10分别为 M。同时，还可作为多响应荧光探针检测DMF溶液中的甲苯，检测限分别为9.16*10 ^-3 M。Al-MOF的结构通过FTIR、¹ H NMR、SEM、TAG、PXRD和元素分析表征。PXRD表明Al-MOF的结构保持了较高的水稳定性和pH稳定性。水样和蔬菜的应用表明，Al-MOF对Fe ³⁺离子具有高灵敏度检测。
