本项目旨在构建一系列用于极性乙烯基单体聚合的弱相互作用型Lewis酸碱对，其特征是Lewis酸、碱中心之间的结合力既有一定强度又可被极性单体断裂。这种Lewis酸碱对兼具分子内协同催化能力和酸碱协同催化能力，有望成为高稳定性、高活性催化剂，将有效促进多种极性乙烯基单体聚合，获得具有多种微观结构、性能优异、可满足多种需求的高分子材料。深入考察Lewis酸、碱中心间相互作用力的大小与可催化单体种类、活性之间的关系，揭示催化剂结构与聚合活性之间的关系；通过动力学、计算机密度泛函（DFT）计算阐明聚合反应机理，为新型催化剂的设计提供新思路和理论依据。

The project focuses on the design and synthesis of a series of novel weak interacting Lewis Pair complexes for polymerization reaction of polar vinyl monomer. The binding way between acid and base is weak force that can be broken by polar vinyl monomer. The weak interacting Lewis pair will show intramolecular cooperation effect and acid-base cooperation effect simultaneously. The target complexes will be catalysts with high stabilization and good activity, and also will give high performance polyolefin products with multiple microstructures, which can be used in versatile applications. The project will reveal internal rule between catalyst structure and polymer structure by in-depth study the relationship between catalyst structure and polymerization activity. Furthermore, the project will study polymerization mechanism based on the DFT calculation and kinetic study, and will provide the opportunity for designing other new catalyst.
