Disclosed are a dimer and an organic light emitting device including the same, which emits high-quality blue light and is excellent in luminous efficiency, heat resistance and film forming processability. The spiro dimer has a structure of the following formula, and the organic light emitting device of the present invention includes a first electrode having a high work function, a second electrode having a low work function, and the spiro dimer, At least one organic compound layer positioned between the second electrode.n n n n n n n n Where connector K is (Wherein n are each independently an integer of 0 to 6), or (Wherein n are each independently an integer of 0 to 4), R may be the same or different from each other, hydrogen or substituted or unsubstituted alkyl having 1 to 10 carbon atoms, aryl, alkoxy, heteroaryl, amine, alcohol, Aldehyde, or carboxylic acid. |
