报告题目：From single-site catalysts and supramolecular assemblies to metal-organic frameworks (MOFs) and porous organic polymer (POPs): Bridging homogeneous and heterogeneous catalysis
报 告 人：SonBinh T. Nguyen
This presentation will discuss the efforts by our research groups at Northwestern University and Argonne National Laboratory in trying to bridge homogeneous and heterogeneous catalysis through the use of supramolecular environments and porous materials, such as metal-organic frameworks (MOFs) and porous organic polymer (POPs), as platforms for deploying homogeneous catalysts.
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. However, given the enormous diversity of potential structures and chemical functional groups that can be incorporated into the pores of MOFs and POPs, 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. Most importantly, recent developments in MOF and POP synthesis have given rise to catalytically active materials with unprecedented stability and novel activity that were not observed in solution.
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 has coauthored over 260 manuscripts, held over 30 patents, and is the recipient of many awards. His expertise is in the broad areas of catalysis, chemical synthesis, soft material synthesis, and biologically inspired materials chemistry. In 2014, he was named a Highly Cited Researcher by Thompson-Reuters.
