Tailoring Pyridone Linkers to Control Properties of MOFs For Use in Gas Storage, Gas Separation, Catalysis and Energy Technologies

在过去的几十年里，人们已经制备了许多金属有机骨架(MOF)，以期在气体储存、气体分离、催化等方面具有潜在的应用价值。不幸的是，它们中很少有表现出允许MOF内部发生化学变化的热稳定性和化学稳定性。因此，为了开发一种更坚固的材料在能源技术中的应用，我们选择了吡啶酮连接物来制备新闻MOF。由于其平坦的拓扑结构和在混合金属MOF中诱导金属均匀分布的能力，吡啶酮连接物被选中。目前，还没有研究使用吡啶酮单元来构建一维、二维或三维的无限网络。吡啶酮是一种异位配位，可以很容易地结合到任何有机片段中，从而允许几个金属离子以对比的方式包含在MOF中。从晶体工程、电化学、磁化学和光化学的角度来看，它们可预测的金属团簇组织引起了我们的注意，因为当目标是新技术的发展时，这些性质是必要的。

Over the past few decades, many Metal Organic Frameworks (MOFs) have been prepared for their potential applications such as gas storage, gas separations, catalysis and other applications. Unfortunately very few of them have shown the thermal and chemical stability that allow the interior of MOFs to be chemically altered. Therefore, to develop a more robust material for applications in energy technologies, we have selected pyridone linkers for the preparation of news MOFs. Pyridone linkers have been chosen for their flattened topologies and their ability to induce homogenous distribution of metals in the Mixed-Metal MOFs. At present, no studies have used pyridone unit to build an infinite network one, two or three dimensional. Pyridone is a heterotopic coordination site that can be easily incorporated into any organic fragment and thereby allows the inclusion of several metal ions in contrable manner into the MOFs. Their predictable organization of metals in clusters have attracted our attention from crystal engineering, electrochemical, magnetochemical and photochemical point of view as these properties which are necessary imperative when the target is the development of new technologies.**
