Title: “Abiological Self-Assembly: Predesigned Metallacycles and Metallacages via Coordination”

Abstract: In the last two dozen years, abiological (non-biological) self-assembly has emerged as a major, active and cutting-edge area of chemistry. Many attempts to mimic nature’s elegant self-assembly processes with hydrogen bonds were met with limited success, particularly in the formation of large, finite assemblies with well-defined shapes and sizes, due to the lack of directionality of weak interactions, and the necessity of accurately positioning many dozens of these interactions to obtain functional assemblies. During the early 1990’s, Stang pioneered and developed the use of dative, metal-ligand interactions and coordination-driven self-assembly for the formation of large, nanoscale complex, two (2D) and three (3D) dimensional assemblies, with well-defined shapes. Furthermore, coordination-driven self-assembly represents a “bottoms-up” methodology for the manufacturing of nanoscale species of enormous significance in modern nanotechnology. These self-assembled molecules have potential applications in the biomedical fields. A couple of the self-assembled rhomboids show promising antitumor activity as demonstrated in the Figure below:

Biography of Prof. Stang:

Peter J. Stang is the David P. Garner Distinguished Professor of Chemistry at the University of Utah. He received his B.S in 1963 at DePaul University in Chicago and his Ph.D. with Professor Andrew Streitwieser at UC-Berkeley in 1966. After  two years as an NIH Postdoctoral Fellow with Paul V. R. Schleyer at Princeton University he joined the faculty at the University of Utah where he rose through the ranks and has remained until now. At Utah he served as Chair of the Department of Chemistry from 1989-1995 and Dean of the College of Science from 1997-2007. Stang’s research involves coordination driven self-assembly of novel metalla-cycles and metalla-cages. His contributions to this field have resulted in numerous awards and recognitions, among them Election to the US National Academy of Sciences and The American Academy of Arts and Sciences, Foreign Member of the Chinese Academy of Sciences, The Award of the National Medal of Science by President Obama in 2011, The ACS Priestly Medal in 2013, the Chinese Government “International Cooperation Award in Science and Technology” Awarded by President Xi Jinping in 2016 as well as several Honorary Doctorate Degrees.
