报告摘要：

Nanocrystals exhibit a wide  range of unique properties (e.g., electrical, optical, optoelectronic, catalytic, etc.) that depend sensitively on their  size and shape, and are of both fundamental and practical interest. Breakthrough strategies that will facilitate the design and synthesis of a large diversity of nanocrystals with different properties and controllable size and shape in a simple and convenient manner are of key importance in revolutionarily advancing the use of nanocrystals for a myriad of applications in lightweight structural materials, optics, electronics, photonics, optoelctronics, magnetic  technologies, sensory materials and devices, catalysis, drug delivery, biotechnology, and among other emerging fields. In this talk, I will elaborate four general and robust strategies for  crafting a rich variety of functional 0D 1D, shish-kebab, and Janus  nanocrystals with precisely controlled dimensions (e.g., plain,  core/shell and hollow nanoparticles; plain and core/shell nanorods; nanotubes; and Janus nanoparticles) by capitalizing on a set of rationally designed unimolecular star-like, bottlebrush-like, worm-like, and Janus block copolymers, respectively, as nanoreactors. These four strategies are effective and able to produce oil-soluble and water-soluble monodisperse nanocrystals, including metallic, ferroelectric, magnetic, luminescent, semiconductor, perovskite, and their core/shell structures, which represent a few examples of the kind of nanocrystals that can be produced using these techniques. The applications of these functional nanocrystals in energy conversion and storage (e.g., dye-sensitized solar cells, perovskite solar cells, photocatalysis, LEDs, thermoelectrics, ferroelectrics, and batteries) will also be discussed.

Dr. Zhiqun Lin is currently Professor of Materials Science and Engineering at the Georgia Institute of Technology. He received the B.S. degree in Materials Chemistry from Xiamen University, Fujian, China in 1995,  the Master degree in Macromolecular Science from Fudan University, Shanghai, China in 1998, and the PhD degree in Polymer Science and Engineering from University of Massachusetts, Amherst in 2002. He did his postdoctoral research at University of Illinois at Urbana-Champaign. He joined the Department of Materials Science and Engineering at the Iowa State University as an Assistant Professor in 2004 and was promoted to Associate Professor in 2010. He moved to Georgia Institute of Technology in 2011, and become a Professor in 2014. His research interests include polymer-based nanocomposites, block copolymers, polymer blends, conjugated polymers, quantum dots (rods, tetrapods and wires), functional nanocrystals (metallic, magnetic, semiconducting, ferroelectric, multiferroic, upconversion and thermoelectric) of different architectures (plain, core/shell, hollow and Janus), solar cells (perovskite solar cells, organic-inorganic hybrid solar cells and dye sensitized solar cells), batteries, photocatalysis, electrocatalysis, thermoelectrics, hierarchically structured and assembled materials, and surface and interfacial properties. He has published more than 245 peer reviewed journal articles (with an h-index of 68), 13 book chapters, and 5 books. Currently, he serves as an Associate Editor for Journal of  Materials Chemistry A, and an editorial advisory board member for  Nanoscale. He is a recipient of Frank J. Padden Jr. Award in Polymer Physics from American Physical Society, an NSF Career Award, a 3 M Non-Tenured Faculty Award, and an invited participant at the National Academy of Engineering’s 2010 US Frontiers of Engineering Symposium. He became a Fellow of Royal Society of Chemistry in 2014, a Japan  Society for Promotion of Science (JSPS) Fellow in 2015, and an American Association for the Advancement of Science (AAAS) Fellow in 2018.
