TRUXENE DERIVATIVE AND ORGANIC ELECTROLUMINESCENCE DEVICE INCLUDING THE SAME

摘要

A truxene derivative having good layer forming properties during layer formation and an organic electroluminescent device including the same. The truxene derivative may be represented by Formula 1:;;A layer including the truxene derivative in the organic electroluminescent device may have a decreased number or concentration of convex-concavo () shapes, and performance limitations caused by non-uniformity in each layer of the organic electroluminescent device (for example, short circuiting or uneven light emission due to non-uniformity in an applied electric field) may be thereby prevented or reduced.
