“…PP-Br was characterized by FT-IR spectroscopy. The spectra clearly indicated the disappearance of the C−Cl stretching resonance around 763 cm −1 (Figure S3 of the Supporting Information), 14 thus indicating the completion of the phenyl−phenyl coupling. To confirm further the structure of the polymeric networks, the polymer was characterized at the molecular level by solid-state 31 P NMR (Figure 2).…”

A quaternary phosphonium and tertiary phosphorus functionalized microporous polymer was obtained via nickel(0)-catalyzed Yamamoto-type cross-coupling reaction. The integration ratio of signals (quaternary phosphonium to tertiary phosphorus atoms) was close to 3:2. The polymer networks were stable toward water, base, and acid, and indeed no change in surface area was observed even after the material was treated with 10 M HCl. The pore size distribution calculated by the Horvath–Kawazoe method indicated the presence of micropores with a mean width of about 0.7 and 1.4 nm. Their apparent BET specific surface areas can be tuned (from 650 to 980 m2 g–1) by changing the counteranions (Br– to F–). It displays high intrinsic catalytic activity for the reaction between epoxide and CO2 (yield: 98%, 1 atm). Pd nanoparticles supported on the polymer networks were also prepared, which exhibits high catalytic activity for cross-coupling reaction between 1-chlorobenzene and phenylboronic acid (yield: >95.8%).
