Novel Functionalized Microporous Organic Networks Based on Triphenylphosphine

This article describes the synthesis and functions of phosphine or phosphine oxide functionalized networks (PPP or PPPO; PP=porous polymer). These materials were predominantly microporous and exhibited high surface areas ( S BET : 1284 and 1353 m 2  g −1 for PPP and PPPO, respectively), with high CO 2 (2.46 and 3.83 mmol g −1 for PPP and PPPO, respectively) uptake capacities. Pd nanoparticles can be simply incorporated into the functionalized networks (PPPPd or PPPOPd) 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 PPPPd system, which was higher than that obtained when PPPOPd (53.2 %) or [Pd(PPh 3 ) 4 ] (38.2 %) was used as the catalyst. The superior catalytic ability of PPPPd can be attributed to the structural features that incorporate triarylphosphine within a microporous structure.
