| Abstract: | This article describes the synthesis and functions of phosphine or phosphine oxide functionalized networks (PP? P or PP? PO; PP=porous polymer). These materials were predominantly microporous and exhibited high surface areas (SBET: 1284 and 1353 m2 g?1 for PP? P and PP? PO, respectively), with high CO2 (2.46 and 3.83 mmol g?1 for PP? P and PP? PO, respectively) uptake capacities. Pd nanoparticles can be simply incorporated into the functionalized networks (PP? P? Pd or PP? PO? Pd) through a facile one‐step impregnation. A yield of 98 % was obtained in the Suzuki reaction between 1‐chlorobenzene and p‐tolylboronic acid with the PP? P? Pd system, which was higher than that obtained when PP? PO? Pd (53.2 %) or Pd(PPh3)4] (38.2 %) was used as the catalyst. The superior catalytic ability of PP? P? Pd can be attributed to the structural features that incorporate triarylphosphine within a microporous structure. |
