Ortho-substituted Benzene Derivatives and Organic Light Emitting Devices Comprising The Same
-
Paragraph 0086-0088, (2016/11/28)
The present invention relates to an ortho-substituted benzene derivative organic light-emitting compound and an organic light-emitting device including the same. The compound of the present invention is produced by respectively substituting a benzene derivative (or a carbazole derivative) and a substituted or non-substituted hetero aromatic derivative in first and second positions (ortho substitution) of benzene. High triplet energy is maintained due to a three-dimensional disorder between the ortho-substituted benzene derivative (or carbazole derivative) and the hetero aromatic detivative. A substituent having pore transporting properties is induced in the ortho-substituted benzene derivative (or carbazole derivative) and a substituent having electron transporting properties is induced in the ortho-substituted hetero aromatic derivative. Accordingly, pore injecting and transporting properties and electron injecting and transporting properties are excellent, so that the same can be usefully used as an excellent bipolar-type organic light-emitting compound. The compound of the present invention has excellent heat stability, quantum efficiency, electric current efficiency, electricity efficiency, and phosphorescent (blue, green, and red) properties, so that the same can be usefully used as an effective phosphorescent host material.COPYRIGHT KIPO 2015
