有机硼化合物是近年来广泛研究的一类非金属催化剂, 其在环氧烷烃参与的开环均聚合和共聚合方面展现了良好的适用性, 但二元亲电亲核双组分催化体系在加入大量的反应单体后由于稀释效应带来的熵不利因素往往导致活性减小或失活的问题, 同时也难以制备大分子量的聚合物材料. 基于此, 本文主要综述了本课题组设计的分子内同时含有亲电和亲核中心的双功能有机硼-季铵盐和有机硼-季鏻盐催化体系的研究进展, 重点梳理了此类双功能有机硼催化剂的设计脉络和设计原则, 对比了双功能和双组分有机硼催化体系之间的聚合反应机理, 总结了利用双功能有机硼催化剂在环氧烷烃开环聚合制备脂肪族聚醚、环氧烷烃和二氧化碳共聚合制备二氧化碳基聚碳酸酯、环氧烷烃和环状酸酐共聚合制备聚酯等方面的内容, 展望了有机硼催化剂在高分子合成化学方向的未来和趋势.

Organoboron compounds are a class of non-metallic catalysts that have been extensively studied in recent years and have shown excellent applicability for ring-opening homopolymerization of epoxides and copolymerization of epoxides with other comonomers. However, the binary electrophile/nucleophile catalytic systems often have reduced activity or be deactivated due to the entropic disadvantage under dilute conditions, and it is also difficult to afford polymer materials with high molecular weight. This paper reviews the progress of bifunctional organoboron-quaternary ammonium/phosphonium salt catalytic systems containing both electrophilic and nucleophilic centers in one molecule that was designed by our group, focuses on the design concepts and principles of such bifunctional organoboron catalysts, compares the polymerization mechanisms between bifunctional and binary organoboron catalytic systems, and summarizes the use of bifunctional organoboron catalysts in the ring-opening polymerization of epoxides to prepare aliphatic polyethers, the copolymerization of epoxides and carbon dioxide/cyclic anhydride to prepare polycarbonates/polyesters. The future and trend of organoboron catalysts in polymer chemistry were prospected.
