Welcome to
ONG, Tiow-Gan WEBSITE
Tiow-Gan Ong (TGO) received his B.Sc. from Winona State University in 1994 and went on to earn his Ph.D. in Inorganic Chemistry from the University of Kentucky in 2000. He further enhanced his expertise during postdoctoral appointments at University of California, Santa Barbara (2000-2001) and University of Ottawa, Canada (2001-2003), where he later served as a lecturer (2003-2006). In 2006, TGO returned to Asia to establish his independent research career at Institute of Chemistry, Academia Sinica (Taiwan, China) as an Assistant Research Fellow. Over the following years, he rose to the rank of Research Fellow and served as Academic Deputy Director of the Institute, while also holding joint-appointments as Professor at National Taiwan University (China), University of Malaya (Malaysia) and the University of Central Florida (USA). In 2025, He joined the family of the Chinese University of Hong Kong, Shenzhen (CUHK-SZ) as Professor at School of Science and Engineering (SSE).
TGO group is internationally known for pioneering contributions at the interface of organometallic chemistry, carbone science and catalysis. His work has opened a new frontier by bridging fundamental bonding concepts with practical catalytic application and chemical synthesis. Notable breakthroughs include:
• Selective C–H/C-O bond activation: Development of nickel-mediated catalysts that can selectively activate C–H and C-O bonds. These systems have been transformed strategies for construction and streamlined access to variable chemical compounds and material.
• New class of C(0) science: Discovery and advancement of carbone and carbodicarbene (CDCs) as a distinct class of C(0) ligands. His insights have reshaped paradigms in Frustrated Lewis Pairs (FLP) chemistry, metal-free catalysis and radical-mediated transformations, offering new ways to merge one-and two-electron process within a single ligand framework.
• Isolation of unstable dicarbon (C2): His landmark isolation of the elusive dicarbon (C2), which published in Nature Chemistry represents a milestone in carbon science and has become reference point for rethinking the limits of chemical bonding.
