in situ
reversible control over ligand binding processes at transition metal complexes can enable advances in switchable and tunable catalysis. After a brief overview of different approaches to controlling ligand binding, this Perspective details the development of "pincer-crown ether" ligands that contain a rigid pincer backbone and a hemilabile aza-crown ether unit that enables cation-modulated hemilability. Applications of pincer-crown ether complexes in small molecule activation and catalysis are discussed, culminating in a set of design principles for ligands capable of cation-modulated ligand binding.
The development of cation-responsive "pincer-crown ether" complexes featuring tunable hemilability is reviewed in the context of switchable and tunable catalysis. |

Miller received a B.S. from the University of Chicago in 2005, and a Ph.D. at the California Institute of Technology in 2011 working with John Bercaw and Jay Labinger. After a postdoctoral fellowship at the University of Washington, Seattle with Karen Goldberg and James Mayer, Alex joined the faculty at the University of North Carolina at Chapel Hill as an Assistant Professor of Chemistry in July 2012. His research group is using thermochemical and kinetic mechanistic studies to guide the development of tunable catalysts for chemical synthesis and alternative energy applications.
