Abstract
Abstract A porous polycarbazole polymer containing fullerene (FulCP) was designed in and prepared via ball-milling method this work. Meanwhile, based on the property that fullerene can hybridize with metals, a kind of porous polycarbazole containing fullerene palladium complex (FulCP-Pd) was synthesized by coordinating FulCP with Pd(PPh3)4. The FulCP-Pd was used as a heterogeneous catalyst in the deallylation reaction. During the synthesis of FulCP, the influence of ball-milling and traditional solvent methods on Brunauer–Emmett–Teller specific surface area of FulCP were explored. The results show the specific surface area of FulCP prepared by ball-milling method (1015 m2 g−1) is higher than that by traditional solvent method (920 m2 g−1). In the study of deallylation, the groups of electron donor and electron acceptor have no effect on the reaction. The conversion efficiency of FulCP-Pd with different substrates ranges from 76% to 92%, and the conversion of allyl phenyl ether is the highest (92%). After using five times, the catalytic effect barely shows obvious decrease (85%). This work is not only to discuss the influence of two preparation methods on the porous materials, but also to explore the attachment of fullerene into porous polymer to fabricate a heterogeneous catalyst matrix, which can hybrid with metal complex to be used for heterogeneous catalysis.
