a (3,5)-connected binodal (63)(69·8)-gra net with binuclear [Zn2(μ2-OH)(COO)]2+ clusters, while 2 shows a novel (4,4,5,9)-connected 4-nodal net constructed from the unique Zn(II)-K(I) heterometal rod-like substructures. The results indicate that the disposition of the 2-methylimidazolyl groups of bis(imidazole) ligands have a significant effect on structural diversity. Moreover, the photoluminescence
摘要 两种新颖的三维(3D)柱层状金属有机骨架(MOFs),即[Zn2(μ2-OH)(boaba)(1,4-bmimb)]n (1)和[Zn5K2(μ2- H2O)2(boaba)4(1,2-bmimb)2(H2O)2]·H2O}n (2),通过水热反应制备(H3boaba=3,5-bis-oxyacetate-benzoic acid; 1,4 -bmimb=1,4-双((2-甲基-1H-咪唑-1-基)甲基)苯;1,2-bmimb =1,2-双((2-甲基-1H-咪唑-1-基) )甲基)苯)。值得注意的是,1 展示了一个具有双核 [Zn2(μ2-OH)(COO)]2+ 簇的 (3,5)-连接双节点 (63)(69·8)-gra 网,而 2 展示了一个新的 (4,4 ,5,9)-连接的 4 节点网络,由独特的 Zn(II)-K(I) 异质金属棒状子结构构成。结果表明,双(咪唑)配体的2-
