In the past decade, the use of visible light to promote organic transformations has gained intense attention. In this study, we developed a template-directed synthesis method to use homogeneous Ru and Ir photocatalysts as structure-directing templates and succeeded to prepare a series of photocatalyst-encapsulating metal–organic frameworks ([email protected]) with zeolite-like structures. The open channels and polyhedral cages of MOFs effectively dispersed the encapsulated photocatalysts and facilitated the transport of reactants and products, leading to boosted catalytic activity and good reusability toward important organic reactions such as aerobic oxidation reaction of benzyl halides and the cyclization of tertiary anilines and maleimides under visible light. Moreover, we also demonstrate the versatility and universality of our templating strategy. It not only can form MOFs which cannot be accessed by other synthesis methods, but also can encapsulate various commercially available homogeneous photocatalysts into MOFs. This work explores an avenue to prepare heterogeneous photocatalysts to catalyze value-added reactions.

模板定向合成具有增强光催化活性的包封金属-有机骨架的光催化剂

在过去的十年中，使用可见光促进有机转化受到了广泛的关注。在这项研究中，我们开发了一种模板导向的合成方法，使用均相的Ru和Ir光催化剂作为结构导向模板，并成功制备了一系列具有沸石样结构的光催化剂包封金属有机骨架（[受电子邮件保护]）。MOF的开放通道和多面体笼有效地分散了封装的光催化剂，并促进了反应物和产物的运输，从而提高了催化活性，对重要的有机反应（如苄基卤的需氧氧化反应以及叔苯胺和马来酰亚胺的环化反应）具有良好的可重复使用性。在可见光下。而且，我们还将展示我们的模板策略的多功能性和普遍性。它不仅可以形成无法通过其他合成方法获得的MOF，而且可以将各种市售的均相光催化剂封装到MOF中。这项工作探索了制备非均相光催化剂以催化增值反应的途径。
