Quan Li

Senior Research Fellow, Adjunct Professor

Li received his Ph.D. in Organic Chemistry from Chinese Academy of Sciences (CAS), Shanghai, China. In February of 1998, he was promoted to a full professor of Organic Chemistry and Medicinal Chemistry in CAS. He held visiting appointments in Department of Chemistry, Hong Kong University of Science & Technology, Hong Kong (1996-1997); Department of Protein Engineering, Life Sciences Division, Atomic Energy Commission of France, Saclay/CEA, Paris, France (1998-1999); Institute of Organic Chemistry, University of Göttingen, Germany (1999-2000); and Department of Chemistry, University of Oregon, USA (2001-2004). Also, he was Alexander von Humboldt Fellow in Germany (1999). In 2004, Li joined LCI as a Senior Research Fellow and the director of Organic Synthesis Laboratory, and he is an adjunct professor in the Chemical Physics Interdisciplinary Program at LCI.

Li’s Research is currently supported by Air Force Office of Scientific Research (AFOSR), Air Force Research Laboratory (AFRL), Department of Energy (DOE), National Science Foundation (NSF), Department of Defense Multidisciplinary University Research Initiative (MURI), Ohio Board of Regents and Samsung Electronics.

Scholarly, Creative & Professional Activities


Research Interests

Synthetic chemistry plays a key role in the advancement of material sciences and life sciences. Research in these fields is often limited by the scope of available synthetic methods and the availability of materials. With that in mind, Li’s research focuses on molecular design and synthesis of novel advanced materials, and synthesis and self-assembly of well-defined molecular structures on a nanometer length scale. Such materials include nature inspired light-harvesting materials, fast switching optoelectronic materials, light-driven chiral molecular switches or motors, water-soluble and organo-soluble functionalized hybrid gold nanorods, shape-persistent molecules, liquid crystalline monomers and their networks, and biologically active synthetic and natural compounds, all of which offer tremendous new possibility in applications such as renewable solar energy, photodisplay, tunable photonics, intelligent energy saving devices, AFM molecular tips, biosensors, and drug delivery as well as fundamental science. Presently, graduate students and postdoctoral fellows are actively involved in Li’s research.
