Chemistry of bowl-shaped aromatic compounds “Buckybowls”

Chemistry of bowl-shaped aromatic compounds“Buckybowls”

Bowl-shaped π-conjugated compounds including partial structures of the fullerenes, which are called "buckybowls", are of importance not only as model compounds of fullerenes but also as their own chemical and physical properties. Heteroatom-containing buckybowls (heterobuckybowls) have also been expected to exhibit unique physical characters. For example, in solution they show the characteristic dynamic behavior such as bowl-to-bowl inversion. On the other hand, they sometimes favor stacking structure in a concave-convex fashion in the solid state, giving excellent electron conductivity. Furthermore, some buckybowls are conceivable to possess the bowl-chirality if the racemization process, as equal as bowl-to-bowl inversion, is slow enough to be isolated. However, very few buckybowls/heterobuckybowls has been achieved for preparation mainly due to their strained structure, and no report on the preparation of chiralbowls has appeared. In addition, most of thus-reported procedures are performed under severe reaction conditions, limiting the sort of the introducible atoms/functional groups.

In the present works, we develop the rational route to the various kinds of buckybowls/heterobuckybowls using the organic synthesis approach. Representative projects are as follows:

  • A.Syntheses and properties of novel buckybowls including hetero-buckybowls and chiral buckybowls.
  • B.Construction of novel fullerenes and carbon nanotubes from buckybowls.
  • C.Application of buckybowls to nano-link materials
  • D.Buckybowl supramolecules
Chemistry of Fullerenes

Chemistry of“Fullerene”

We are aiming to elucidate the basic principle in order to synthesize novel compounds efficiently and selectively based on the chemical and physical properties of organic molecular. For this purpose, we are performing systematic studies of substittuent and solvent effects of novel reactions to propose the mechanism, considering the steric and electronic factor governing the reaction. It is necessary to investigate molecular orbital theoretically and kinetically to this goal.

Main Research theme

  • A.Development of Novel Reaction Based on Electron Acceptability of Fullerenes and Quinone/Carbonyl Compounds
  • B.Solvent Effects and Reaction Kinetics
  • C.Study on Molecular Orbital of Cage Compounds
  • D.Application of Water-soluble Fullerene Nano Particle
  • E.Elucidation of Structure and Reactivity of Fullerene Multiadduct
  • F.Development of New Fullerene Materials
Chemistry of metal nanocluster catalysts

Chemistry of “metal nanocluster catalysts”

  • A.Preparation of size-selective gold nanocluster supported by hydrophilic polymers and its application to aerobic oxidation catalyst.
  • B.Synthetic application using metal nanocluster catalyst.
  • C.Development of designer metal nanocluster catalyst using the highly- functionalized protective polymers.
  • D.Catalytic activity of metal nanoclusters under the laser-irradiated conditions.
