Research in the Li Group

The past few decades have seen a significant growth in the field of supramolecular chemistry. These supramolecular structures created by non-covalent interaction possess self-healing abilities, high physical performance while maintaining processibility, recyclability scenarios, and stimulus-responsive behavior. Our research is focused on metal-mediated supramolecular chemistry to construct a series of 2D and 3D architectures with precise shapes and sizes. Our specific research interests include:

  1. Design, synthesis and self-assembly of the core structures of supramolecules. Typically, these giant 2D or 3D structures have molecular weights more than 10,000 Da.
  2. Incorporating polymers chains into supramolecular core through either pre- or post-assembly modification.
  3. Characterization of supramolecules using mass spectrometry, e.g., Matrix-Assisted Laser Desorption/Ionization (MALDI),  Electrospray Ionization (ESI), and Ion Mobility-Mass Spectrometry (IM-MS).

Fundamental advances in synthesis, self-assembly, and characterization of metallo-supramolecules will advance the design of supramolecules, and ultimately allow predictable incorporation of desired properties and functionality into supramolecular architectures with molecular level precision.
