Patent ID: 7888170

Claim:
A method of manufacturing an electronic element comprising a pair of electrodes formed on a substrate, a mesoporous film having tubular mesopores oriented in one direction, the mesoporous film being formed between the pair of electrodes so as to be in contact with the pair of electrodes, a conjugated high molecular compound held in the tubular mesopores, and a third electrode which is electrically insulated from the conjugated high molecular compound and formed so as to be in contact with the mesoporous film, the method comprising a step of forming the conjugated high molecular compound in the tubular mesopores, which step comprises: (i) a step of forming the mesoporous film which is made up so as to contain tubular molecular assemblies of a surfactant having a uniform diameter, which are oriented in one direction; a step of removing the surfactant from the tubular mesopores of the mesoporous film; a step of performing treatment so that surfaces of the tubular mesopores after removal of the surfactant obtain hydrophobicity; and a step of introducing the conjugated high molecular compound subsequently to the hydrophobicizing treatment; and (ii) a step of forming the pair of electrodes and the third electrode.
