共价有机骨架（COF）是具有明确的二维或三维分子结构的结晶多孔固体。尽管结构规律性为这种新型多孔材料提供了很高的催化潜力，但迄今为止还没有任何例子。在此，我们报告了新型COF材料COF-LZU1的首次应用，用于高效催化。易于制备的亚胺连接的COF-LZU1具有二维重叠层状片结构，使其与金属离子的结合成为可能。通过简单的后处理，合成了含Pd(II)的COF，Pd/COF-LZU1，其在催化Suzuki-Miyaura偶联反应中表现出优异的催化活性。 Pd/COF-LZU1在催化方面的优越用途体现在广泛的反应物范围和优异的反应产物收率（96-98%），以及催化剂的高稳定性和易于回收性。我们期望我们的方法将进一步促进设计和使用功能性 COF 材料进行催化的研究。
Covalent organic frameworks (COFs) are crystalline porous solids with well-defined two- or three-dimensional molecular structures. Although the structural regularity provides this new type of porous material with high potentials in catalysis, no example has been presented so far. Herein, we report the first application of a new COF material, COF-LZU1, for highly efficient catalysis. The easily prepared imine-linked COF-LZU1 possesses a two-dimensional eclipsed layered-sheet structure, making its incorporation with metal ions feasible. Via a simple post-treatment, a Pd(II)-containing COF, Pd/COF-LZU1, was accordingly synthesized, which showed excellent catalytic activity in catalyzing the Suzuki-Miyaura coupling reaction. The superior utility of Pd/COF-LZU1 in catalysis was elucidated by the broad scope of the reactants and the excellent yields (96-98%) of the reaction products, together with the high stability and easy recyclability of the catalyst. We expect that our approach will further boost research on designing and employing functional COF materials for catalysis.
