Toshiaki Enoki (Japanese: 榎 敏明; born December 4, 1946) is a Japanese physical chemist. After earning his Ph.D. from Kyoto University, he was appointed as a research associate at the Institute for Molecular Science in 1977. His early research focused on the electronic and magnetic properties of organic conductors and graphite intercalation compounds , with particular emphasis on hydrogen adsorption into graphitic galleries. In 1987, he joined the Tokyo Institute of Technology (now the Institute of Science Tokyo) as an associate professor and was promoted to full professor in 1991. During this period, his research interests shifted toward graphene - a single atomic layer of graphite and related carbon-based materials, particularly nanosized graphene, or nanographene. Enoki’s primary focus became the unique geometrical dependence of nanographene sheets in determining their electronic and magnetic properties. In 1996, M. Fujita theoretically predicted the existence of a localized nonbonding state - known as an edge state at the carbon atoms along the zigzag edges of a graphene sheet. Enoki later confirmed the presence of this edge state experimentally using scanning tunneling microscopy, He has contributed to understanding of the electronic, magnetic, and chemical properties of nanographene and related carbon-based materials.
