A Zn(II)-MOF [Zn(2)(tzba)(DMF)]·0.5DMF (1) (H(2)tzba = 4-(1H-tetrazol-5-yl) benzoic acid, DMF = N,N'-dimethylformamide) has been solvothermally synthesized and characterized. 1 is a three-dimensional (3D) microporous framework possessing an unusual multi-nodal (3,3,6)- or (4,4,4,4)-connected topological net. The small-sized pores, open metal sites, phenyl π systems and tetrazolyl groups of tzba(2-) decorating the pore with high polarity enable 1 to attract strongly for CO(2), which leads to high sorption heat for CO(2) and significant selectivities for CO(2) over H(2) and N(2). In addition, 1 and desolvated 1' display strong and weak blue luminescence in solid state, respectively, being mainly related to the framework vibration due to the residing and releasing of DMF molecules in the channel.
一种 Zn(II)-MOF [Zn(2)(tzba)(DMF)]·0.5DMF(1)(H(2)tzba=4-(1H-四唑-5-基)苯甲酸,DMF=N,N'-二甲基甲酰胺)已通过溶剂热合成法合成并进行了表征。1 是一种具有不寻常的多节点(3,3,6)或(4,4,4,4)连接拓扑网络的三维(3D)微孔框架。小分子尺寸的孔、开放的金属位、苯环π系统和四唑基修饰孔的高极性使得 1 能够强烈吸附 CO(2),这导致 1 对 CO(2)的吸附热很高,对 CO(2)相对于 H(2)和 N(2)的选择性很高。此外,1 和去溶剂化的 1'在固态分别显示出强和弱的蓝色发光,这主要与由于通道中 DMF 分子的驻留和释放而引起的骨架振动有关。
