摘要: 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 Fe 3+, Sr 2+ and SiO 3 2− in water, which is mainly due to the significant enhancement effect of these ions on the fluorescence intensity of Al-MOF. Especially, Fe 3+ ions are rarely able to induce MOFs fluorescence enhancement. The limit of detection for three kinds of ions is …
