Composition for organic semiconductor insulating films, and organic semiconductor insulating film

摘要

The purpose of the invention is to provide: a composition for an organic semiconductor insulating film, which is capable of forming an insulating film that exhibits excellent hydrophobicity and smoothness of the surface, while having excellent electrical stability; and an organic semiconductor insulating film obtained by using the composition for an organic semiconductor insulating film. The present composition contains a polysiloxane and an organic polymer compound. The polysiloxane is a polyhedral silsesquioxane having an oxetanyl group and/or an oxetanyl group containing silicon compound represented by the following formula (1). In the formula (1), each of R1-R3 independently represents a monovalent organic group (provided that at least one of R1-R3 is a monovalent organic group having an oxetanyl group); and each of v, w, x and y independently represents 0 or a positive number (provided that w and at least one of v, x and y are positive numbers).;

主权项

1. A composition, comprising: (A) a polysiloxane, and (B) an organic polymer compound,
wherein the polysiloxane (A) is at least one of a cage-shaped silsesquioxane comprising an oxetanyl group, and a silicon compound comprising an oxetanyl group and represented by formula (1): wherein each R1, each R2 and each R3 independently represent a monovalent organic group comprising an alkyl group comprising 1 to 6 carbon atoms, an aralkyl group comprising 7 to 10 carbon atoms, an aryl group comprising 6 to 10 carbon atoms, a (meth)acryloyl group, an epoxy group or an oxetanyl group, with the proviso that at least one of R1, R2 and R3 is a monovalent organic group comprising an oxetanyl group; the monovalent organic group is optionally substituted by a halogen atom, a hydroxy group, an alkoxy group, an aryloxy group, an aralkyloxy group or an oxy group; w represents a positive number; and v, x and y each independently represent 0 or a positive number, with the proviso that at least one of v, x and y is a positive number, wherein the organic polymer compound (B) comprises a polyvinylphenol, and the composition is suitable for an organic semiconductor insulating film.
