<p>A fluorene derivative is provided to form an organic layer in an organic electronic device, and to impart increased efficiency, reduced driving voltage and improved stability to an organic electronic device. A fluorene derivative is represented by the following formula 1. In formula 1, R1 is a group represented by the following formula 2, wherein R2 is a group represented by the following formula 3 or 4. In formula 2, R3 and R4 are the same or different, and each represents a substituted or non-substituted C6-C30 aryl, or a substituted or non-substituted C5-C30 heteroaliphatic ring or heteroaromatic ring group, wherein R3 and R4 are optionally bonded to each other to form an aryl, heteroaryl or aliphatic fused ring; X is -N-Ar11, O or S, wherein Ar11 is H, a C1-C30 alkyl, C6-C30 aryl or C5-C30 heteroaryl. In formulae 2 and 4, each of L1 and L2 represents a direct bond, C6-C30 arylene or C5-C30 heteroarylene. In formulae 1, 3 and 4, Ar1, Ar2, Ar3, Ar4, Ar5, Ar6, Ar7, Ar8, Ar9, and Ar10 are the same or different, and each represents H, halogen, amino, nitrile, nitro, C1-C30 alkyl, C2-C40 alkenyl, substituted or non-substituted C6-C30 aryl, substituted or non-substituted C5-C30 heterocyclic group, substituted or non-substituted C6-C30 arylamino, or substituted or non-substituted C5-C30 heteroarylamino group.</p> |
