Biography
Dr. Cheuk-Wai SO is currently in the Division of Chemistry and Biological Chemistry, School of Physical and Mathematical Sciences as Assistant Professor since August 2008. He received his Bachelor and Ph.D. degrees from the Chinese University of Hong Kong. He was an Assistant Professor in the Chinese University of Hong Kong before working as a Humboldt Research Fellow at the Universität Göttingen in 2005. Prior to joining NTU, he was a JSPS Research Fellow at the University of Nagoya. He was awarded with Sir Edward Youde Memorial Fellowship, Humboldt Research Fellowship and JSPS Postdoctoral Fellowship. His current research interests lie in the field of low valent silicon chemistry, catalysts for olefin polymerization and functional materials based on boron containing π-conjugated system.
Research Interests
A. "Unusual" Main Group Organometallic Chemistry
Our research group is focused on the synthesis of novel organometallic complexes derived from main group elements, particularly calcium, boron, aluminum, silicon and phosphorus, with emphasis on the elucidation of the electronic structures and unprecedented reactivates, which lead to the possible application in catalysis, activation of small molecules, organic synthesis and material sciences. One of our goals is to prepare new organometallic complexes with unusual oxidation state, coordination number and bonding.

B. Heterobimetallic Catalysts
We are interested in the synthesis of heterobimetallic complexes incorporated with two different main group elements or transition metals. It is anticipated that two metals with different properties combined together in a complex can apply synergetically to an entirely new electronic and chemical behavior, thus enabling possible new catalytic activity. Such complexes can be applied as catalysts in olefin polymerization and ring opening polymerization.

C. New pi-electron System
Our research is aimed at the synthesis of new pi-electron complexes containing organic pi-conjugated frameworks and main group elements. It is well known that organic pi-conjugated systems serve as electronic and optoelectronic devices due to the delocalization of pi-electron, while main group elements have unique electronic and structural properties. Incorporation of main group elements into the organic pi-conjugated systems can change their inherent functions, which lead to an entirely new electronic behavior. We anticipate that such pi-electron complexes can serve as new-generation optoelectronic devices
