Two CuxIy-based copper–organic frameworks with multiple SBUs have been successfully synthesized. Both the compounds exhibit high performance for I2 sorption and release.
Herein, a novel 3-dimensional (3D) Cu(II) metal-organic framework (MOF), [Cu3(μ2-O)2(p-tr2Ph)2(HCOO)][NO3]∙3DMF∙3H2O (compound 1), which is constructed by directly interlocking regionalized hollow two-dimensional (2D) layers, has been conceived and solvothermally synthesized. Such...
On the basis of our conception of in-situ fabricating multifunctional metal-organic frameworks (MOFs), a binuclear Co-MOF [Co3(μ2-OH)(bpydc)(Htpim)2]·3NO3-·4MeOH·5DMA (1) (H2bpydc = (2,2’-bipyridine)-5,5’-dicarboxylic acid, Htpim = 2,4,5-tri(4-pyridyl)imidazole, DMA = N,N-dimethylacetamide) with additionally...
By utilizing a mixed-ligand strategy, a novel multicomponent Cu-metal−organic framework (MOF) (JLU-MOF107) has been successfully synthesized. JLU-MOF107 has an unusual hierarchical structure-mimicking distribution structure. The triangular 4,4′,4″-benzene-1,3,5-triyl-tribenzoate (BTB) ligand and the binuclear Cu cluster form a threefold interpenetration layer, while the linear ligand 1,4-phenylene-4,4′-bis(1,2,4-triazole) (p-tr 2 ph) and tetranuclear Cu cluster form a noninterpenetration pillared-layer structure. Then, the two types of layers are connected by tetranuclear Cu clusters to construct the final sandwichlike framework. JLU-MOF107 exhibits good water and humidity stability. Due to the presence of various active sites and pores, JLU-MOF107 shows an outstanding performance for CO 2 capture (171.0 cm 3 g −1 at 273 K). Density functional theory (DFT)-based calculations further prove the interactions between CO 2 molecules and multiple active sites. The innovative synthesis of this multicomponent structure offers a new perspective on making hierarchical porous materials and multifunctional MOFs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
