AN AROMATIC COMPOUND AND AN ORGANIC LIGHT EMITTING DIODE COMPRISING AN ORGANIC LAYER COMPRISING THE SAME

摘要

An aromatic compound is provided to obtain an organic light emitting device with low driving voltage, high efficiency and high brightness due to excellent thermal stability and light-emitting property. An aromatic compound is represented by the chemical formula 1: M1-(B)n-M2. In the chemical formula 1, B is a single bond, a substituted or non-substituted C1-C60 alkylene group, substituted or non-substituted C5-C60 cyclo alkylene group, substituted or non-substituted C5-C60 arylene group, substituted or non-substituted C2-C60 heteroarylene group or a divalent linker showing -N(Z1)-, wherein the Z1 is hydrogen, substituted or non-substituted C1-C60 alkyl group or substituted or non-substituted C5-C60 aryl group; n is an integer of 1-10; and M1 and M2 are each other independent.
