Patent ID: 8344368

Claim:
A compound of the following Formula 1: wherein t is 1 or 2, and Z is represented by the following Formula 2a or Formula 2b; n and m are independently an integer of 1 to 7, and u is an integer of 1 to 8, s an integer of 0 to 10, and r is 0, 1 or 2, q is an integer of 1 to 3, and when q is 2 or more, substituent groups in a bracket are the same as or different from each other, R 1 to R 3 are independently selected from the group consisting of hydrogen, deuterium, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, and a substituted or unsubstituted arylamine group, in the case where n or u is 2 or more, R 1 s are the same as or different from each other and adjacent R 1 s may be connected to each other to form a monocycle or a fused cycle including an aliphatic cycle, an aromatic cycle or a hetero cycle, and in the case where m is 2 or more, R 2 s are the same as or different from each other, and adjacent R 2 s may be connected to each other to form a monocycle or a fused cycle including an aliphatic cycle, an aromatic cycle or a hetero cycle, Ar is selected from the group consisting of a substituted or unsubstituted arylene group, a substituted or unsubstituted heterocyclic group, and a substituted or unsubstituted arylamine group, and in the case where s is 2 or more, Ar are the same as or different from each other, Ra to Rh are independently selected from the group consisting of hydrogen, deuterium, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, and a substituted or unsubstituted arylamine group, and adjacent groups of Ra to Rh may be connected to each other to form a monocycle or a fused cycle including an aliphatic cycle, an aromatic cycle or a hetero cycle.
