A mononuclear Cu(II)-based metal-organic framework as an efficient heterogeneous catalyst for chemical transformation of CO2 and Knoevenagel condensation reaction

Metal–Organic Frameworks in Heterogeneous Catalysis: Recent Progress, New Trends, and Future Perspectives

“…The high catalytic performance of the catalyst was rationalized by the synergetic effect of the two metallic components and the unique hollow structures. 86 A plethora of other CO 2 cycloaddition MOF-based systems have been developed, e.g., the zinc-based ZIF-23, 87 the solvent-free amine-functionalized solvothermal (s)-or microwave (m)-assisted NH 2 -MIL-101(Al), 88 the zirconium-based VPI-100 (Cu) and VPI-100 (Ni), 89 flexible Zn-based MOFs, 90 as well as the mononuclear Cu II MOF 91 and Cd II MOF. 92 The catalytic systems for CO 2 insertion into epoxides are summarized in Table 1, where decorated, de novo synthesized, and pristine MOF-based catalysts are included.…”

SC–SC Anion-Assisted Linker Exchange within a Three-Dimensional Cu(II)-Triazole Framework: A Luminescent Probe for S2–

“…Interestingly, an anion-induced SC–SC transformation resulted in {[Cu 0.5 (MTP)­(H 2 O)]­(NO 3 )} n ( 1a ), which exhibited a kagóme network (kgm) with a Schlafli symbol of {3 2 ·6 2 ·7 2 }. 1a can also be generated via mixing this ligand and Cu­(NO 3 ) 2 ·2.5H 2 O in a 20 mL capped vessel containing water and EtOH mixed solution and evaporating at room temperature for 1 week . Our initial experiments on the luminescent properties indicated that 1a represented the first example of a triazole-based ligand showing selective luminescence-based Fe 3+ detection.…”

Assembly of Two Self-Interpenetrating Metal–Organic Frameworks Based on a Trigonal Ligand: Syntheses, Crystal Structures, and Properties

“…By virtue of abundant N atoms as Lewis basic sites in the framework, MOF 2 can be investigated and implemented to catalyze the Knoevenagel condensation reaction. − The prepared block crystals were soaked in fresh toluene for 30 min and further dried in air for 2 h. In a typical reaction, malononitrile (1.1 mol) and substrates with various functional groups (1.0 mmol) were dissolved in 6 mL of toluene in the presence of MOF 2 (100 mg), which was continually heated at 80 °C for 4 h under slow stirring. The catalytic resultant was measured and calculated by the GC method.…”
