Challenge for Construction of Metal Organic Frameworks with Photosensitizer and Application as New Solid Catalysts

近年来，金属有机骨架（MOFs）的化学性质得到了迅速发展。大多数MOF研究都集中在利用小气体分子的高微孔隙率来存储和分离小气体分子。然而，最近的许多报告表明，活性官能团可以加入到mof中，以创建具有应用价值的混合材料。同时，维生素B12及其衍生物由于其丰富的氧化还原和配位化学性质，被用作许多化学转化的有效催化剂。为了发挥mof和B12的优势，我们采用吸附法将维生素B12衍生物固定在具有光物理化学性质的mof中，然后催化反应。本研究合成了一种新型光敏Ru-MOF，并探索了Ru-MOF- b12化合物在固态下的脱氯反应和1,2-迁移反应。

The chemistry of metal-organic frameworks (MOFs) has evolved rapidly in recent years. Most MOF research has focused on storage and separation of small gaseous molecules by taking advantage of their high microporosities. However, numerous recent reports have demonstrated that active functional groups can be incorporated into MOFs to create hybrid materials with applications. At the same time, vitamin B12 and its derivatives are used as efficient catalysts for a number of chemical transformations due to their rich redox and coordination chemistry. To develop the advantage of MOFs and B12, we adopt absorption method that enables immobilization of vitamin B12 derivatives into the MOFs which has photo-physicochemical property, then to catalyze the reaction. In this study, a novel photosensitive Ru-MOF was synthesized and Ru-MOF-B12 compound was explored for the dechlorination reaction and 1,2-migration reaction in the solid states.
