Abstract
1,3,5-Triazine functionalized nanoporous polymer (PDVB-triazine-xs, where x stands for the molar ratio of DVB and triazine) was synthesized from copolymerization of 1,3,5-triacryloylhexahydro1,3,5-triazine with divinylbenzene (DVB) cross-linker under solvothermal conditions. The resultant PDVB-triazine-xs act as efficient supports for Pd(OAc)2, which gives the Pd/PDVB-triazine-xs catalyst. Characterizations by N2 isotherms, TEM images, and solid NMR 13C spectrum show that Pd/PDVB-triazine-xs has large surface areas, abundant nanopores, and successful copolymerization of DVB with triazine functional monomer, which showed a high cross linking degree. XRD and elemental maps show Pd was successfully loaded into PDVB-triazine-xs supports, which showed very good dispersion in the samples. Pd/PDVB-triazine-xs showed excellent catalytic activity and good recyclability in Suzuki–Miyaura cross coupling reaction. The preparation of Pd/PDVB-triazine-xs will develop functional nanoporous polymer based catalysts or catalyst supports in the Suzuki–Miyaura reaction.
