Unconventional Design Approaches for Controlling and Modifying Reactivity of Post-metallocene Olefin Polymerization Catalysts
DescriptionThis project looks at unconventional strategies for influencing and controlling the nature and reactivity of olefin polymerization catalysts. While the influence of substituents adjacent to the catalytic site is renowned, the idea of “indirect” steric substituent effects exerted from a remote location away from the approaching olefin molecule is unexplored. This counter-intuitive phenomenon, which has been observed in preliminary results, is intriguing and will be investigated in detail by various synthetic, spectroscopic, and computational techniques. It is envisioned that enhanced catalytic performance will be developed, while mechanistic implications for related catalyst systems can be derived. Using related “indirect” substituent effects, the design and preparation of complexes capable of engaging in intramolecular interactions that are previously unknown for post-metallocene catalysts will be undertaken, and complementary studies towards model compounds to illustrate the feasibility of these interactions will be performed. These developments may pave the way for unprecedented advances in the coordination polymerization of selected polar olefins.
