【摘要】 金属有机骨架材料具有孔道大小可调节、骨架结构可修饰的特性,在吸附与分离方面展现出优异的性能,然而这类材料的稳定性仍然是一个极具挑战性的难题。我们利用金属簇结构基元法,成功地组装了一例新型多核金属簇的三维稳定多孔配位聚合物。该化合物是由四核金属簇结构基元构筑的一种具有优良化学稳定性的三维多孔化合物,不论是长期暴露在空气中,还是在酸碱水溶液以及多种有机溶剂中都能维持很好的结晶状态与吸附性能,这种稳定的金属有机骨架材料在多方面具有潜在的应用价值。更多还原

【Abstract】 Metal-organic frameworks have outstanding adsorption and separation ability due to their unique tunable and modifiable porosity. However, their stabilities are still challenging problems. Recently, we have successfully assembled a kind of porous stable 3-D MOFs by utilizing metal-cluster building unit strategies. The porous frameworks with an extraordinary chemical stability were constructed by tetranuclear metal-cluster. It can maintains its structural intensity and adsorption function no matter exposed to air for several months or in acidic and basic aqueous solutions and many kinds of organic solutions, which has potential application values in many ways.更多还原
