Abstract
Abstract A method for the formation of monomolecular adsorption films of a silane compound having a diacetylene bond is described. The silane compound is chemically adsorbed on a substrate through ═SiO-- bonds and the resultant film is significantly reduced in number of defects such as pinholes. When the monomolecular film is irradiated with actinic light, the diacetylene bonds are convered into a conjugated diacetylene polymer. Similarly, a built-up film of a desired number of monomolecular layers of a silane compound having an acetylene bond formed on a substrate by chemical adsorption and a corresponding number of monomolecular layers of an aliphatic acid or alcohol having an acetylene bond and alternately deposited on the first-mentioned layer is also provided.
