金属有机框架（MOF）以其吸附各种气体的能力而闻名。使用 MOF 来储存和释放生物活性气体，特别是一氧化氮 (NO) 和一氧化碳 (CO)，一直是人们感兴趣的主题。为了阐明这些气体的结合机制和几何形状，使用钻石光源的同步加速器辐射对一组表现出有前景的气体吸附特性的 MOF 进行了原位单晶 X 射线衍射 (scXRD) 研究。 NO 和 CO 被引入活化的 Ni-CPO-27 和相关的 Co-4,6-二羟基间苯二甲酸酯 (Co-4,6-dhip) 中。两种 MOF 对 CO 和 NO 都表现出很强的结合亲和力，但 CO 更容易受到水的竞争性共吸附的影响。此外，我们表明形态在这两个系统的脱水难易程度方面可以发挥重要作用。金属有机框架已证明在存储和释放生物活性气体方面具有前景。在这里，使用同步加速器辐射的原位单晶 X 射线衍射研究阐明了活性骨架 Ni-CPO-27 和 Co-4,6-二羟基间苯二甲酸酯中一氧化氮和一氧化碳气体的结合机制和几何形状。
Metal-organic frameworks (MOFs) are well known for their ability to adsorb various gases. The use of MOFs for the storage and release of biologically active gases, particularly nitric oxide (NO) and carbon monoxide (CO), has been a subject of interest. To elucidate the binding mechanisms and geometry of these gases, an in situ single crystal X-ray diffraction (scXRD) study using synchrotron radiation at Diamond Light Source has been performed on a set of MOFs that display promising gas adsorption properties. NO and CO, were introduced into activated Ni-CPO-27 and the related Co-4,6-dihydroxyisophthalate (Co-4,6-dhip). Both MOFs show strong binding affinity towards CO and NO, however CO suffers more from competitive co-adsorption of water. Additionally, we show that morphology can play an important role in the ease of dehydration for these two systems. Metal–organic frameworks have demonstrated promise for the storage and release of biologically active gases. Here, an in situ single crystal X-ray diffraction study using synchrotron radiation elucidates the binding mechanisms and geometries of nitric oxide and carbon monoxide gases in activated frameworks Ni-CPO-27 and Co-4,6-dihydroxyisophthalate.
