| Our group has recently reported the development of cyclophane-based bisimine ligand scaffolds capable of complexing nickel and palladium polymerization catalysts. These catalysts have greatly increased thermal stability as well as novel branching selectivities in the polymerization of olefins compared to traditional Brookhart-type bisimine catalysts. Our current research is focused on the development of novel sterically constrained bisimine ligands for thermally robust polyemerization catalysts. Our results have shown that a tigher, more sterically congested environment increases the stability of the catalyst, especially at high temperatures. By varying the active site cavity of the embedded metal center, the stability, reactivity, and selectivity of the polymerization catalysts can be tuned. |
