To provide a peroxo complex which forms an organic molecule having a very simple ligand through self-assembly, the organic molecule itself has a nanotube-like structure of a high specific surface area and is stable at ordinary temperature in the atmosphere and a method for utilizing the peroxo complex as a catalyst for oxidation reactions.
The peroxo complex which is stable in the atmosphere and has a high specific surface area due to the so far unobtainable nanotube form is obtained by mixing a peptide lipid with a metal to form metal-coordinated organic nanotubes, dispersing the nanotubes in a mixed solvent, e.g. an acetonitrile-water mixture, and adding a peroxide, e.g. hydrogen peroxide. By using the peroxo complex obtained as a catalyst for oxidation reactions, alcohols can be oxidized to ketones or carboxylic acids.
