Research Area

• Organosilicon and related organo main-group element chemistry

Research Subjects

• Silicon and germanium-based sigma- and pi-electron systems
• Heavy group-14 element analogs of carbenes
• Isolable group-15 element dicoordinate radicals
• Triarylphosphine-based redox systems
• Development of novel functionalization reaction of heavy group element compounds

Overview of Research

Our research projects are focusing on the creation of new compounds involving heavier main group elements such as Si, Ge, Sn, P, and B to discover the unique structural characteristics and electronic properties that can be applied as new functional materials for the next generation. Recent progress in our group includes the development of unique silicon-based sigma and pi-electron systems, isolable dialkylphosphinyl radical, and triarylphosphine-based redox systems. In our laboratory, we aim to build the systematic view in bonding, structure, reactions, and properties covering the chemistry of all main group elements.
