摘要：

Three metal-organic frameworks (MOFs), [Co-2(BPDC)(2)(4-BPH) center dot 3DMF](n) (1), [Cd-2(BPDC)(2)(4-BPH)(2)center dot 2DMF](n) (2) and [Ni-2(BDC)(2)(3-BPH)(2) (H2O)center dot 4DMF](n) (3) (H2BPDC=biphenyl-4,4'-dicarboxylic acid, H2BDC=terephthalic acid, BPH=bis(pyridinylethylidene)hydrazine and DMF=N,N'-dimethylformamide), have been solvothermally synthesized based on the insertion of heterogeneous BPH pillars. Framework 1 has "single-pillared" MOF-5-like motif with inner cage diameters of up to 18.6 angstrom. Framework 2 has "double pillared" MOF-5-like motif with cage diameters of 19.2 angstrom while 3 has "double pillared" 8-connected framework with channel diameters of 11.0 angstrom. Powder X-ray diffraction (PXRD) shows that 3 is a dynamic porous framework. (C) 2012 Elsevier Inc. All rights reserved.
