到達したものである。Furthermore, it is possible to control the oxidation-reduction potential of the ionic aggregate according to the characteristics described in (11) above, and by coexisting the conductive material with such an ionic aggregate, it is possible to achieve extremely high electrochemical properties. We have discovered that it is possible to provide a new electrode material that can be used in many applications. In particular, by changing the combination of poly elements and hezo elements, the redox potential on the mediator side can be changed dramatically without changing its structure (Kaggjn structure A), and the host side has multipolar reaction selectivity. In addition, by making these ionic associations exist on a conductive material, we discovered that it is possible to create a standard electrode material and have arrived at the present invention.
