| Popis: | A carbazole functionalized mesoporous organic polymer (CzMOP) was synthesized by carbazolyl oxidative coupling polymerization. The nitrogen-rich CzMOP material was used as a good organic support for loading palladium nanoparticles to develop heterogeneous catalysts. The CzMOP and Pd nanoparticle supported MOP (Pd@CzMOP) was fully characterized using Brunauer–Emmett–Teller (BET) surface area analysis, X-ray diffraction analysis (XRD), Fourier transform infrared (FTIR) spectroscopy, solid-state 13C NMR spectroscopy, field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and thermogravimetric analysis (TGA). The Pd@CzMOP material exhibited excellent catalytic activity towards Suzuki–Miyaura cross coupling between aryl halides and phenyl boronic acid substrates. The catalytic system was found to be recycled up to five times without significant loss of catalytic activity. |
