摘　　要：A new flexible 3D porous metal-organic framework （MOF） with 1D open nanotube, [Co2（/zs-CTAl）（dpe）（H20）2]n-6n（H20） （1） （CTA = cyclohexane-1,2,4,5-tetracarboxylic acid, dpe = 1,2-di（4-pyridyl） ethylene） has been prepared and structurally character- ized. Meanwhile, each 1D nanotubes filled with 1D water chain with dimension of 13.711 ~ 12.275/~2. Compound 1 represents a new example that collapse/deform upon dehydration/hydration and shows adsorb 1-120 selectively over organic solvents.A new flexible 3D porous metal-organic framework (MOF) with 1D open nanotube,[Co2(μ5-CTAI)(dpe)(H2O)2]n·6n(H2O)(1) (CTA=cyclohexane-1,2,4,5-tetracarboxylic acid,dpe=1,2-di(4-pyridyl) ethylene) has been prepared and structurally characterized.Meanwhile,each 1D nanotubes filled with 1D water chain with dimension of 13.711 × 12.275 2.Compound 1 represents a new example that collapse/deform upon dehydration/hydration and shows adsorb H 2 O selectively over organic solvents.
