Charge transport film, method for producing the same, and light-emitting element and photoelectric conversion element using the same

摘要

The present invention provides a charge transport film which is prepared through subjecting a coating film including at least one charge transporting agent to an atmospheric pressure plasma treatment, wherein electron transfer between the charge transport film and a substance that contacts with the charge transport film is promoted, and deterioration in performance due to diffusion and mixing or crystallization of low molecular weight components, such as a charge transporting agent, incorporated in a cured film is suppressed also in the case of film formation by a wet method, and which exhibits excellent charge transportability and stability over time; a production method with good productivity; and a light-emitting element and photoelectric conversion element equipped with the charge transport film, the atmospheric pressure plasma treatment being preferably a treatment that applies plasma, which is generated using a plasma generating apparatus and conveyed using an inert gas, to the coating film.

主权项

1. A charge transport film formed through subjecting a coating film comprising at least one charge transporting agent to an atmospheric pressure plasma treatment, wherein electron transfer between the charge transport film and a substance that contacts with the charge transport film is promoted, wherein the charge transporting agent is a compound having a polymerizable group, and comprises a compound represented by the following Formula (III):
R1R2C═C(R3)—(C═O)—O-L-Ar1—(C═O)—O—Ar2—R4  Formula (III) wherein, in Formula (III), Ar1 and Ar2 each independently represents an arylene group; L represents a divalent linking group selected from the group consisting of alkylene groups having from 1 to 22 carbon atoms, arylene groups having from 6 to 22 carbon atoms, and —O—, or a divalent linking group obtained by combining two or more linking groups selected from the group consisting of alkylene groups having from 1 to 22 carbon atoms, arylene groups having from 6 to 22 carbon atoms, and —O—; and R1, R2, R3 and R4 each independently represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms.
