method for producing monomolecular adsorptionsfilmen or monomolecular layers structured films using silanen, acetylene or diacetylenbindungen included.

摘要

This invention relates to a method for the formation of monomolecular adsorption films of a silane compound having a diacetylene bond. 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 converted 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. These films have wide utility in electronic fields.
