CHEMISORPTION SUBSTANCE FOR FORMING THIN FILM AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a new chemisorption substance for forming a thin film, capable of forming a coating film of monomolecular layer by the chemical adsorption on a substrate surface, transparent and stable to the light of visible range, activated by ultraviolet rays and forming intermolecular crosslinks by ultraviolet irradiation. SOLUTION: The objective compound is expressed by formula X ((n) is 1-20; X is a halogen), e.g. the compound of formula II. The production process of the compound of formula I comprises e.g. the 1st step to perform aldol condensation reaction of (A) benzaldehyde with (B) 4-acetylbenzoic acid to obtain (C) a chalcone derivative of formula III having carbonyl group bonded to the 4'-site of the benzene ring of chalcone skeleton and the 2nd step to carry out the dehydrohalogenation reaction of (D) an alcohol having chalcone skeleton and derived from the component C with (E) a compound of the formula: SiX4 (X is a halogen) in an inert gas atmosphere to obtain the objective chalcone derivative having the characteristic group of formula IV and an O-SiX3 group.
