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.
金属有机框架材料（MOFs）以其吸附各种气体的能力而闻名。将MOFs用于生物活性气体尤其是一氧化氮（NO）和一氧化碳（CO）的储存和释放，一直是人们感兴趣的课题。为了阐明这些气体的结合机制和几何结构，利用钻石光源的同步辐射对一组具有良好气体吸附性能的MOFs进行了原位单晶X射线衍射（scXRD）研究。将NO和CO引入到活化的Ni-CPO-27和相关的4,6-二羟基间苯二甲酸钴（Co-4,6-dhip）中。两种MOF对CO和NO都表现出很强的结合亲和力，然而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体系的脱水难易程度中可以发挥重要作用。
