英文摘要: The development of recoverable and reusable polymer catalysts with high catalytic efficiency is of considerable significance and has been a mainstay in the field of polymer materials research. Despite the fact that a large number of traditional polymer supports have been reported, they usually displayed relatively low catalytic activity and selectivity compared to the homogeneous catalysts owing to their low surface area, small pore size and the increased diffusion resistance. This project addresses the design, synthesis and characterization of novel functionalized ordered mesoporous phenol-formaldehyde resin and its application for immobilizing (S)-diphenylprolinol silyl ether organocatalyst. We propose to explore the catalytic performances of these novel mesoporous polymeric organocatalysts in the asymmetric reactions and further test their durability and subsequent reusable efficiency. Meanwhile, we investigate to engineer the structure and chemistry of the catalysts to achieve a better catalytic performance and fundamentally understanding their influence on the catalytic reactions. Based on various characterizations, the correlation of the catalytic properties to the physical structure, chemical composition and surface properties of the mesoporous resin-based organocatalysts will be discussed. This success
