Title:

ARYLAMINE COMPOUND, ORGANIC ELECTROLUMINESCENCE ELEMENT, AND ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2024/033884

Kind Code:

A1

Abstract:

An objective of the present invention is to provide, as a material for an organic electroluminescence (EL) element having high efficiency and high durability, an organic compound represented by general formula (I) and having excellent hole injection/transport performance, electron-blocking ability, and excellent properties with high stability in a thin film state, and is to provide an organic EL element having high efficiency and high durability by using the compound. In the formula, A represents a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group, B represents a substituted or unsubstituted carbazolyl group, C represents an unsubstituted naphthylene group, R represents an unsubstituted aromatic hydrocarbon group, an unsubstituted aromatic heterocyclic group, or an unsubstituted condensed polycyclic aromatic group, L1 to L3 represent a single bond, an unsubstituted divalent aromatic hydrocarbon group, an unsubstituted divalent aromatic heterocyclic group, or an unsubstituted divalent condensed polycyclic aromatic group. An arylamine compound of the present invention has excellent heat resistance, and also has good hole-transporting ability. The organic EL element using the compound in a hole transport layer, an electron blocking layer, a light-emitting layer, and a hole injection layer of the organic EL element exhibited good element properties.
