Lewis pair (LP) chemistry has shown broad applications in the catalysis field. However, one significant challenge has been recognized as the instability for most homogeneous LP catalysts upon recycling, thus inevitably leading to dramatic loss in catalytic activity. Additionally, current heterogeneous LP catalysts suffer from low surface area, which largely limits their catalytic efficiency, thereby restricting their potential applications. In this work, we report the successful introduction of LPs, classical and frustrated, into a metal-organic framework (MOF) that features high surface and ordered pore structure via a stepwise anchoring strategy. Not only can the LP be stabilized by the strong coordination interaction between the LP and MOF, but the resultant MOF-LP also demonstrates excellent catalysis performance with interesting size and steric selectivity. Given the broad applicability of LPs, our work therefore paves a way for advancing MOF-LP as a new paradigm for catalysis.

刘易斯对（LP）化学已在催化领域中显示出广泛的应用。然而，已经认识到一个重大挑战是大多数均质LP催化剂在再循环时的不稳定性，因此不可避免地导致催化活性的显着损失。另外，当前的非均相LP催化剂具有低的表面积，这极大地限制了它们的催化效率，从而限制了它们的潜在应用。在这项工作中，我们报告了通过逐步锚固策略将经典的和受挫的LP成功引入到具有高表面和有序孔结构的金属有机框架（MOF）中。不仅可以通过LP和MOF之间的强大协调互动来稳定LP，但是所得的MOF-LP还具有出色的催化性能，并且具有令人感兴趣的尺寸和空间选择性。鉴于LP的广泛应用，因此我们的工作为推动MOF-LP成为催化的新范例铺平了道路。
