Abstract:
     Coordination-driven self-assembly as a bottom-up approach has witnessed a rapid growth in the past few decades. Challenges still remain, however, within both the construction of giant architectures in terms of high efficiency and complexity, as well as effective structural characterizations. Inspired by Nature, especially the self-assemblies of DNA and peptides, we have constructed a series of giant 2D and 3D metallo-supramolecular architectures with increasing complexity through rational design of the ligands. A combination of various techniques, including NMR, MS, TEM, STM, AFM, as well as UHV-LT-STM have been applied toward the characterizations of these intricate structures. The success of the self-assemblies has revealed the potential of such strategies of constructing giant supramolecular architectures in a controlled manner. The manifold characterizations, on the other hand, have paved the way for their future applications.

Bio: Dr. Bo Song obtained his bachelor’s degree in biomedical engineering from Zhejiang University in 2011. Then he got three years’ training on synthetic organic chemistry at Lanzhou University and got MS in 2015. Afterwards he came to the United States and got his PhD in December 2019 from the University of South Florida under the supervision of Prof. Xiaopeng Li. His research focus during his PhD includes supramolecular self-assemblies and mass spectrometry. He is currently a postdoctoral scholar with Sir Fraser Stoddart (2016 Nobel Laurate) at Northwestern University, working on artificial molecular machines (AMMs) and mechanically interlocked molecules (MIMs). He has published more than thirty papers on high impact journals including Science, Nature Chemistry, Nature Communications, Journal of the American Chemical Society, Angewandte Chemie International Edition, etc.
