Lecture Title: Metal-organic frameworks (MOFs) as a general platform for the deployment of catalysis

SonBinh T. Nguyen

Northwestern University


This presentation will discuss the efforts by our research groups at Northwestern University and Argonne National Laboratory in exploitingmetal-organic frameworks (MOFs) as platforms for deploying catalysis.

As hybrid materials derived from well-defined molecular building blocks, newly emerged porous materials such as MOFs are natural solid-state 3-D versions of supramolecules. These materials have many of the desirable features of zeolites, such as high surface area and porosity, and can be similarly effective in size- and shape-selective catalysis.[1] However, given the enormous diversity of potential structures and chemical functional groups that can be incorporated into the pores of MOFs, these porous materials have the potential to extend catalysis far beyond the realm of zeolitic chemistry to include enzyme-like behaviors such as adapted flexibility during catalysis, substrate pre-concentration effects, active-site isolation and protection, and tunable hydrophobicity.[2]For example, recent developments in MOF synthesis have given rise to catalytically active materials with unprecedentedstability[3]and novel combinations of activities[4]that were not observed in solution. In addition, a combination of synthetic modulation[5]and post-synthesis modification has allowed us to modulate the nodes of MOFs to tune catalytic activities in the oxidation of sulfides and sulfoxides.

SonBinh T. Nguyen received a doctoral degree in Chemistry under the directions of Profs. Robert Grubbs and Nathan Lewis at Caltech, where he was an NSF and an NDSEG predoctoral fellow. After an NSF postdoctoral fellowship with Prof. K. Barry Sharpless at Scripps, SonBinh began his independent career at Northwestern in 1996, where he is now a Professor of Chemistry. He is also a Senior Fellow in the technical staff at Argonne National Laboratory. At Northwestern, he has held the Dow Research Professorship, the highly prestigious McCormick Professorship of Teaching Excellence and the Directorship of the Integrated Science Program.

SonBinh’s research was recognized with a PECASE (Presidential Early Career Award in Science and Engineering) Award, a National Science Foundation CAREER Award, as well as young investigator awards from the Dreyfus Foundation, the Beckman Foundation, and the Packard Foundation. The Union Carbide Corporation gave him its 1999 Innovation Recognition Award, making him one of the youngest recipients of this award. Nguyen was selected as an Alfred P. Sloan Fellow in 2000 and appointed to our Dow Research Professorship in 2004. In 2008, his work was recognized by an Outstanding Research Achievement award from the Defense Threat Reduction Agency (DTRA). His research has been continuously supported by several DoD agencies such as the AFOSR, the ARO, and DTRA.
