A quinoxaline ring containing compound is provided to improve life span, efficiency and power consumption characteristic of an organic light emitting device. A quinoxaline ring containing compound is represented by a formula(1), wherein each R1, R2, R3 and R4 is independently H, halogen, hydroxy, cyano, substituted or unsubstituted C1-30 alkyl, substituted or unsubstituted C1-30 alkoxy, substituted or unsubstituted C1-30 acyl, substituted or unsubstituted C2-30 alkenyl, substituted or unsubstituted C2-30 alkynyl, substituted or unsubstituted C7-30 aralkyl, substituted or unsubstituted C6-30 aryl, or substituted or unsubstituted C5-30 heteroaryl; each n, a and b is 1 or 2; and L is a simple chemical bond, substituted or unsubstituted C1-30 alkylene, substituted or unsubstituted C7-30 aralkylene, or substituted or unsubstituted C6-30 arylene. An organic light emitting device comprises: a first electrode; a second electrode; and an organic film between the first and second electrodes, wherein the organic film includes the quinoxaline ring containing compound.
