Abstract
A conductive organic thin film includes organic molecules, each of which has: a terminal binding group that is bound with a surface of a substrate by a covalent bond, the terminal binding group being present at one of the ends of the organic molecule; a conjugate group that is polymerized with another molecule, the conjugate group being present in the organic molecule; and a photoresponsive functional group including no active hydrogen, the photoresponsive functional group being present between the terminal binding group and the conjugate group. In the conductive organic thin film, the organic molecules are aligned, and the conjugate group of each molecule is polymerized with the conjugate group of another molecule so that a conductive network is formed. This conductive organic thin film has an optical switching function, having a conductivity that varies in response to irradiation of light.
