Total synthesis, where desired organic- and/or bio-molecules could be produced from simple precursors at atomic precision and with known step-by-step reactions, has prompted centuries-lasting bloom of organic chemistry since its conceptualization in 1828 (Wöhler synthesis of urea). Such expressive science is also highly desirable in nanoscience, since it represents a decisive step towards atom-by-atom customization of nanomaterials for basic and applied research. Although total synthesis chemistry is less established in nanoscience, recent years have witnessed seminal advances and increasing research efforts devoted into this field. In this talk, I will discuss our recent work on introducing and developing total synthesis routes and mechanisms for atomically precise metal nanoclusters (NCs). Due to their molecular like formula and properties (e.g., HOMO-LUMO transition, strong luminescence and stereochemical activity), atomically precise metal NCs could be regarded as “molecular metals” (or metallic molecules / molecular-like metals), holding potential applications in various practical sectors such as biomedicine, energy, catalysis and many others. More importantly, the molecular-like properties of metal NCs are sensitively dictated by their size and composition, suggesting total synthesis of them as an indispensable basis for reliably realizing their practical applications.
Dr. Jianping Xie is currently an Associate Professor at the Department of Chemical & Biomolecular Engineering at National University of Singapore (NUS). He received his B.S. and M.S. in Chemical Engineering from Tsinghua University, China, and his Ph.D. from the Singapore-MIT Alliance (SMA) program. Dr. Xie joined NUS in 2010 and established the BioNanoMetals research group. His group is known for the work on engineering ultrasmall metal nanoclusters for biomedical and environmental applications. Dr. Xie has 140+ publications (e.g., Nat. Commun., JACS, Angewante, Adv. Mater., and ACS Nano), 11000+ citations, an H-index of 59, and 26 highly cited papers (ISI). His research interests include noble metal nanoclusters, nanomedicine, and applied environmental nanotechnology.
