Prof. Naoki Komatsu


Graduate School of Human and Environmental Studies, Kyoto University


 


Carbon-based nanomaterials have been attracting enormous interest due to a wide variety of (potential) applications. Their sophisticated applications mostly require homogeneous properties based on the structural homogeneity. We have applied host-guest chemistry to discriminate the structures of carbon nanotubes (CNTs) such as handedness and diameter as well as the properties such as metallicity [1]. The host molecules designated as “nanotweezers”[1], “nanocalipers”[2], and “nanocage”[3] have been designed, synthesized and applied to CNT separation.

Biography


Naoki Komatsu received his bachelor’s, master’s and doctor’s degrees from Kyoto University in 1986, 1988 and 1993, respectively. He joined Okayama University in 1993 and moved to Kyoto University as Assistant Professor in 1994. In 1997, he worked at Florida State University as a visiting scholar for one year. In 2003, he moved from Kyoto University to Shiga University of Medical Science as Associate Professor. He was promoted to Professor at Kyoto University in 2015. His research concept is to “apply organic chemistry to nanomaterials” including supramolecular chemistry on nanocarbons for their structural separation of and synthetic organic chemistry on inorganic nanoparticles for their functionalization in cancer nanomedicine.
