The present invention provides a carbazole derivative of formula (I) for an organic electroluminescent device:
wherein Y represents a heteroatom selected from N, O, P, S, or a bicyclic or tricyclic heterocyclic ring; and
Ar
1
and Ar
2
each independently represent an alkyl or aryl substituted or unsubstituted aromatic hydrocarbon, or an alkyl or aryl substituted or unsubstituted heterocyclic aromatic hydrocarbon.
본 발명은 화학식 (I)로 표현되며, 상기 식에서, Y는 N, O, P, S, 또는 비시클릭 또는 트리시클릭 헤테로시클릭 고리로부터 선택된 헤테로원자를 나타내며; 그리고 Ar1 및 Ar2는 각각 독립적으로 알킬 또는 아릴 치환된 또는 비치환된 방향족 탄화수소, 또는 알킬 또는 아릴 치환된 또는 비치환된 헤테로시클릭 방향족 탄화수소인, 유기 전기발광 소자용 화학식 (I)의 카바졸 유도체를 제공한다.
