Abstract
A method for producing a chiral metal oxide structure, involves a sol-gel step of allowing a transition metal compound having a bi- or higher dentate chelate ligand to act on a chiral supramolecular crystal of an acid-base complex containing a polymer having a linear polyethyleneimine skeleton and a chiral dicarboxylic acid compound having two carboxyl groups and four or more carbon atoms to form a metal oxide layer on a surface of the chiral supramolecular crystal; and a calcination step of thermally decomposing the organic chiral supramolecular crystal after the sol-gel step to generate a transition metal oxide structure composed of the metal oxide layer prepared with the supramolecular crystal as a template.
