"Cation-Responsive Pincer-Crown Ether Complexes for Tumble Catalysis"
Catalyst performance often depends on the ability of a substrate to bind a transition metal center, but methods to control these substrate binding processes remain elusive. We are harnessing interactions between molecular catalysts and their environment to control organometallic catalysis. Incorporating a crown ether macrocycle into a robust pincer ligand enables the donor properties of such “pincer-crown ether” ligands to be tuned through cation-macrocycle interactions. Mechanistic studies of the dynamic interactions between catalysts, cations, and substrates provide an emerging picture of how cations can tune catalyst performance.
