The synthesis of phosphine-based functional covalent organic frameworks (COFs) has attracted great attention recently. Herein, we present two examples of triphenylphosphine-based COFs (termed P-COFs) with well-defined crystalline structures, high specific surface areas, and good thermal stability. Furthermore, rhodium catalysts with these P-COFs as support material show high turnover frequency for the hydroformylation of olefins, as well as excellent recycling performance. This work not only extends the phosphine-based COF family, but also demonstrates their application in immobilizing homogeneous metal-based (e.g., Rh-phosphine) catalysts for application in heterogeneous catalysis.
基于膦的功能性共价有机框架材料（COFs）的合成近来备受关注。在此，我们展示了两个基于三苯基膦的COFs（称为P-COFs）的实例，它们具有明确的晶体结构、高比表面积和良好的热稳定性。此外，以这些P-COFs作为载体材料的铑催化剂在烯烃氢甲酰化反应中表现出高周转频率以及出色的循环性能。这项工作不仅扩展了基于膦的COF家族，还展示了它们在固定均相金属基（如铑-膦）催化剂以用于多相催化方面的应用。
