Title:
電荷輸送性ワニス
Document Type and Number:
Japanese Patent JP6383984
Kind Code:
B2
Abstract:
A charge-transporting varnish which contains a charge-transporting substance containing fluorine atoms, a charge-transporting substance containing no fluorine atoms, a dopant substance composed of a heteropolyacid, and an organic solvent. The charge-transporting substance containing fluorine atoms is a polymer which is obtained by condensing a triaryl amine compound, an arylaldehyde compound containing fluorine atoms, a fluorene derivative having a carbonyl group and a carbazole derivative having an alkyl group or an alkyl group containing an ether structure in the N-position, and which has a weight average molecular weight of 1,000-200,000. The charge-transporting substance containing no fluorine atoms is an oligoaniline compound. A thin film formed from this charge-transporting varnish is capable of providing an organic EL element having excellent luminance characteristics and durability even in cases where the thin film is used as a single layer between a positive electrode and a light emitting layer in such a manner that the thin film is in contact with the positive electrode and the light emitting layer.
