Abstract
An indolo[3,2,1-jk] carbazole derivative is represented by the following Formula 1. In Formula 1, X is a carbon atom or a nitrogen atom. At least one of X is a nitrogen atom. when X is a nitrogen atom, R is not present. When X is a carbon atom, R is hydrogen, an alkyl group, an alkoxy group, an aryl group, or a heteroaryl group. L is an electron acceptor, and m and n represent an integer of greater than or equal to 1.
Claims13
An indolo[3,2,1-jk] carbazole derivative, in which an indolo[3,2,1-jk] carbazole skeleton and an electron acceptor are combined, and at least one carbon atom of a benzene ring forming the indolo[3,2,1-jk] carbazole skeleton is replaced with a nitrogen atom.
An organic electroluminescence device, comprising an emission layer including an indolo[3,2,1-jk] carbazole derivative, in which an indolo[3,2,1-jk] carbazole skeleton and an electron acceptor are combined, and at least one carbon atom of a benzene ring forming the indolo[3,2,1-jk] carbazole skeleton is replaced with a nitrogen atom.
An organic electroluminescence device, comprising an intermediate layer between a hole transport layer and an emission layer,
- wherein the intermediate layer includes an indolo[3,2,1-jk] carbazole derivative, in which an indolo[3,2,1-jk] carbazole skeleton and an electron acceptor are combined, and at least one carbon atom of a benzene ring forming the indolo[3,2,1-jk] carbazole skeleton is replaced with a nitrogen atom.
