The synthesis of phosphine‐based functional covalent organic frameworks (COFs) has attracted great attention recently. Here, we present two examples of triphenylphosphine‐based COFs (termed as P‐COFs) with well‐defined crystalline structures, high specific surface areas and good thermal stability. Furthermore, the rhodium catalysts using the obtained P‐COFs as support materials show high turnover frequency (TOF) for the hydroformylation of olefins, as well as the excellent recycling performance. This work not only extended phosphine‐based COFs family, but also demonstrated their application in immobilizing homogeneous metal‐based (e.g., Rh‐phosphine) catalysts for heterogeneous catalysis application.
