Professor Zhibin Guan of the University of California-Irvine is supported by the Chemical Catalysis Program in the Division of Chemistry to explore the scope of a new family of Ru (II) complexes which his lab recently discovered and showed that they have catalytic activity towards olefin insertion polymerization and copolymerization of alpha-olefins with polar monomers. Plans are presented to achieve higher activities through catalyst tuning based on the design of various new ligand architectures, and on a better understanding of the catalytic system and the reaction mechanism. Computational modeling will be conducted to complement the experimental mechanistic and activity studies. The polymerization activities of the complexes will be correlated with the structures of the catalysts. The trends observed and the insights gained will guide further design of better Ru-based olefin polymerization catalysts. The copolymerization of olefins with polar monomers continues to be a significant challenge and the proposed research has the potential to lead to better routes to functionalized polyolefins and consequently to new polymeric materials with important specialized applications. The proposed research will provide students and postdoctoral researchers with valuable educational experience in organometallic chemistry, polymerization, catalysis, kinetics, and computational science.

加利福尼亚大学 - 艾尔文大学的Zhibin教授得到了化学催化计划的支持，以探索他的实验室最近发现的新的RU（II）综合体的范围，并证明它们对烯烃插入插入式插入式插入式聚合和alpha-Olefins collpha-Olefins的催化活性。根据各种新配体架构的设计以及更好地理解催化系统和反应机制，提出了通过催化剂调整来实现更高活动的计划。将进行计算模型以补充实验机械和活动研究。复合物的聚合活性将与催化剂的结构相关。观察到的趋势和获得的见解将指导基于RU的烯烃聚合催化剂的进一步设计。 烯烃与极性单体的共聚是一个重大挑战，拟议的研究有可能导致更好地实现功能化聚芬，并因此提供具有重要专业应用的新聚合物材料。拟议的研究将为学生和博士后研究人员提供有宝贵的教育经验，这些教育经验在有机化化学，聚合，催化，动力学和计算科学方面。
