Abstract

A solid material or an oily material for forming an organic thin film is produced by hydrolyzing and condensing at least one kind of organic metal compound expressed by Formula (1) in a lower alcohol-based solvent in the presence of water and an acid with a concentration of 0.5% to 5% by mass in the resultant reaction solution. The solid material or oily material that is obtained is dissolved in an organic solvent, and a substrate is brought into contact with a solution that is obtained to form a highly functional organic thin film on the substrate.

Dependent claims

A method for producing an organic thin film-laminated plate, the method comprising:

process (A):
a process of hydrolyzing and/or condensing at least one kind of organic metal compound expressed by Formula (I) in a lower alcohol-based solvent or a mixed solvent containing the lower alcohol-based solvent in the presence of water and an acid with a concentration of 0.5% to 5% by mass in the resultant reaction solution, or a process of hydrolyzing and/or condensing the organic metal compound in a solvent that contains at least one kind selected from an aliphatic ether-based solvent and an aliphatic ketone-based solvent and does not contain the lower alcohol solvent in the presence of water and an acid of 0.1 to 20 moles with respect to 1 mole of the organic metal compound expressed by Formula (I),
[Chemical Formula 1]
R1nMXm−n (I),
wherein in the formula, R1 represents a hydrocarbon group having 1 to 30 carbon atoms and optionally having a substituent group, or a halogenated hydrocarbon group having 1 to 30 carbon atoms and optionally having a substituent group, M represents at least one kind of metal atom selected from the group consisting of Si, Ge, Sn, Ti, and Zr, X represents a hydroxyl group or a hydrolysable group, n represents any integer of 1 to (m−1), m represents an atomic valence of M, in a case where n is 2 or more, R1 is the same or different in each case, and in a case where (m−n) is 2 or more, X is the same or different in each case;
process (B):
a process of separating a solid content precipitated from the reaction solution of the process (A) or an oily material separated from the reaction solution, or concentrating and drying the reaction solution of the process (A) to obtain the solid content or oily material;
process (C):
a process of mixing the solid material or oily material obtained in the process (B) with at least one kind of solvent selected from the group consisting of a hydrocarbon-based solvent, a fluorine-based solvent, and a silicon-based solvent, and removing insoluble matter as necessary to obtain an organic thin film-forming solution;
and
process (D):
a process of bringing a substrate into contact with the organic thin film-forming solution that is obtained in the process (C) to produce a substrate on which an organic thin film is laminated.
