2019年11月18日，应送彩金的平台王成教授的邀请，美国加州大学Pingyun Feng教授到访，作了题为“Pore Space Control in MOFs for Gas Adsorption and Separation”的学术报告。来自送彩金的平台、材料科学与工程学院及相关学院的师生参加了此次报告会。
Pingyun Feng received her PhD in 1998 from Department of Chemistry, University of California, Santa Barbara (UCSB). After two years of postdoctoral study at Department of Chemical Engineering, UCSB, She joined University of California at Riverside in 2000. Feng’s research focuses on the synthesis, characterization and application of various types of functional solid-state materials. These materials range from porous metal-organic framework materials to high-surface area semiconductors based on metal chalcogenides. Her group has published more than 220 peer-reviewed scientific papers, most of which are in prestigious high-impact journals. Her accomplishments have been recognized by the Beckman Young Investigator Award, NSF CAREER Award, and Camille Dreyfus Teacher-Scholar Award and also an Alfred P. Sloan Fellow award. She is also the Fellow of the American Association for the Advancement of Science. Most recently she received the ACS 2017 F. Albert Cotton Award in Synthetic Inorganic Chemistry.
Metal-organic framework materials (MOFs) are among the most fascinating families of solid-state materials, because of their highly tunable compositions, structures, and properties. In this presentation, strategies for the synthesis of new porous MOFs will be discussed, with the focus on the use of different metallic elements and their various combinations. In addition, the talk will cover our recent efforts and strategies developed on functionalizing MOF for enhancing gas sorption through pore space partitioning and engineering. The pore space of MOF can be engineered by using extra-framework ligands or nested cage-in-cage configurations to tune the gas sorption properties. The development of the optimum pore architectures for enhanced gas sorption will be covered. To maximize the pore space utilization, we are also pursuing a unique synthetic paradigm that is based on the delicate pore space partition by using complementary coordination properties of multitopic ligands and open metal sites.
