<p>The present invention relates to a charge transport material composition for a blue phosphorescent including a carborane compound having one or more aromatic compound be substituted, and to an organic light emitting device for a blue phosphorescent including the same. The blue phosphorescent applying a carborane compound having one or more aromatic compound be substituted has high thermal stability like glass transition temperature (Tg), and has wide energy band gap, while having improved electrical properties like charge mobility to have an effect of excellent physical properties and long lifetime properties of a device.</p> |
