leads to 2,7,12-trisubstituted truxenes. 5,10,15-Triarylated and trialkynylated truxenederivatives are obtained by the reaction of truxenone with aryl Grignard reagents or an alkynyllithium, followed by reduction of the tertiary alcohols with Et3SiH or BF3. syn-5,10,15-Triarylated derivatives were obtained by the base-catalyzed isomerization of the anti derivatives.

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.
