Patent ID: 7078103

Claim:
A conductive organic thin film, comprising organic molecules, each of the organic molecules having: 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, wherein 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, and the conductive network is switchable between different states having first and second conductivities, respectively, the switching being conducted by selecting a wavelength of light projected to the conductive network, and the photoresponsive functional group including no active hydrogen is an azo group (—N═N—).
