Two unprecedented 3D porous anionic metal-organic frameworks, [Me2NH2]2[Cd2(bpdc)3].4dma 1 and [Me2NH2]2[Cd2(NH2bdc)3].4dma 2 (dma = N,N'-dimethylacetamide, bpdc = 4,4'-biphenyldicarboxylate, NH(2)bdc = 2-amino-1,4-benzenedicarboxylate) have been solvothermally synthesized with a dimethylammonium cations template. Both 1 and 2 are constructed from low-symmetry SBUs. 1 has a chiral framework with helical nanotube-like channels, and 2 has a MOF-5-like motif. The fluorescence, N2 adsorption and ion-exchange properties for 1 have been examined.
两种前所未有的三维多孔阴离子金属有机骨架，[Me2NH2]2[Cd2(bpdc)3].4dma 1 和 [Me2NH2]2[Cd2(NH2bdc)3].4dma 2（dma = N,N'-二甲基乙酰胺，bpdc = 4,4'-联苯二甲酸，NH(2)bdc = 2-氨基-1,4-苯二甲酸），采用二甲基铵阳离子模板溶剂热合成。1 和 2 均由低对称 SBUs 构建。1 具有螺旋纳米管状通道的手性骨架，2 具有 MOF-5 样结构。研究了 1 的荧光、N2 吸附和离子交换性能。
