Electron-Conjugated Organic Silane Compound, Functional Organic Thin Film And Production Method Thereof

Abstract

The present invention provides a highly orientated (crystallized) and highly-densely packed functional organic thin film that can be formed in a simple production method by solution method and adsorb tightly to a surface of a substrate, an organic silane compound for preparation of the thin film, and methods of preparing the same. An organic silane compound represented by General Formula; A-B—C—SiX1X2X3 (wherein, A represents a monovalent aliphatic hydrocarbon group having 1 to 30 carbon atoms; B represents an oxygen or sulfur atom; C represents a π-electron-conjugated bivalent organic group; and each of X1 to X3 represents a group giving a hydroxyl group by hydrolysis). A functional organic thin film obtained by using the organic silane compound. A method of producing the organic silane compound, comprising introducing an aliphatic hydrocarbon group A onto a compound represented by General Formula; H—C—H (wherein, C is the same as above) via an ether or thioether bond in Williamson reaction, and additionally introducing a silyl group in reaction thereof with a compound represented by General Formula; X4—SiX1X2X3 (wherein, X1 to X3 are the same as above). A method of producing the functional organic thin film, comprising forming a unimolecular film directly adsorbed on a substrate by hydrolyzing the silyl group in the organic silane compound and allowing the hydrolysate to react with the substrate surface, and washing and removing the unreacted organic silane compound on the unimolecular film with a nonaqueous organic solvent.
