A heterocyclic compound represented by Formula 1:wherein, in Formula 1, groups and variables are the same as described in the specification.
First claim
Opening claim text (preview).
What is claimed is: 1 . A heterocyclic compound represented by Formula 1: wherein, in Formula 1, X 1 is N or C(R 1 ), X 2 is N or C(R 2 ), and X 3 is N or C(R 3 ), wherein i) one selected from X 1 to X 3 is N, and the others thereof are not N; or ii) each of X 1 to X 3 is not N, R 1 to R 3 are each independently hydrogen, deuterium, a C 1 -C 20 alkyl group, a C 1 -C 20 alkyl group substituted with at least one deuterium, a C 1 -C 20 alkoxy group, a C 1 -C 20 alkoxy group substituted with at least one deuterium, or —Si(Q 101 )(Q 102 )(Q 103 ), L 1 and L 2 are each a single bond, L 3 to L 5 are each independently selected from: a single bond; and a C 5 -C 60 carbocyclic group and a C 1 -C 60 heterocyclic group, each unsubstituted or substituted with at least one R 10a , a1 to a5 are each independently an integer from 1 to 5, and Ar 2 is a group represented by Formula 3A, a group represented by Formula 3B, a group represented by Formula 3C, a group represented by Formula 3D, a group represented by Formula 3E, or a group represented by Formula 3F, Ar 1 is a group represented by one selected from Formulae D′-1 to D′-7 and D007 to D279:
