A unique 3D luminescent metal-organic framework, namely [Cd(L)(H₂O)_0.5]·DMF·2.5H₂O (1), where H₂L=3-(tetrazol-5-yl)triazole, has been successfully prepared and characterized. The framework has demonstrated excellent luminescence properties and structural stability in the water system. Notably, the luminescence intensity of 1 was significantly quenched by Cr(Ⅵ) (1 mL of Cr₂O₇^2- or 150 μL of CrO₄^2-, 1 mmol·L^-1), leading to the formation of an "on-off" luminescence silencing system (Cr₂O₇^2-@1), which was capable of accurately detecting Cr(Ⅵ) in the water system. The primary mechanism responsible for luminescence quenching was the Forster resonance energy transfer (FRET) process. Additionally, by removing the involvement of the FRET process, the luminescence intensity of the Cr₂O₇^2-@1 system could be restored, allowing for the highly selective and sensitive detection of ascorbic acid (AA) in water systems. Moreover, it has been demonstrated that 1 can successfully detect AA in vitamin C tablets, yielding recovery rates ranging from 98.20% to 103.33% and relative standard deviations (RSDs) ranging from 1.78% to 3.42%. Based on the findings of this experiment, a luminescent "IMPLICATION" molecular logic gate has been constructed utilizing AA and Cr(Ⅵ) as the chemical inputs, respectively.

Three efficient methods for the synthesis of a series of Cu(Ⅱ) and Cu(Ⅰ) complexes based on imidazo[1,5-a] pyridine derivatives were developed. These methods include the following: (ⅰ) Cu(Ⅱ) salts were used as metal sources and N, N-dimethylformamide was employed as a solvent as well as a reductant to produce Cu(Ⅰ) complexes. (ⅱ) An iodidecontaining compound was utilized as a ligand and iodide source to prepare complexes. An in situ metalligand reaction occurred and an iodide-bridged copper complex was generated. (ⅲ) A series of aldehydes were added to the reaction systems to induce in situ metal-ligand reactions between the aldehydes and the imidazo[1,5-a]pyridine derivatives, producing polydentate ligand scaffolds. Eight complexes were prepared and characterized. The catalytic activities of these complexes toward the ketalization of ketones by ethylene glycol were investigated. With the exception of complex 4, the remaining seven complexes all showed high catalytic activity. The lower activity of 4 may be due to the larger radius of bridging iodide ions and the shorter Cu(Ⅰ)…Cu(Ⅰ) distance.
