An imidazopyrimidine-based compound is provided to improve electron transfer ability of the compound, and produce an organic light emitting diode having low voltage, high efficiency, high brightness, long lifetime and low power consumption. An imidazopyrimidine-based compound represented by the formula(1) is contained in an organic layer of an organic light emitting diode, wherein R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are each independently hydrogen, halogen atom, hydroxyl group, cyano group, optionally substituted C1-C30 alkyl group, optionally substituted C1-C30 alkoxy group, optionally substituted C1-C30 acyl group, optionally substituted C2-C30 alkenyl group, optionally substituted C2-C30 alkynyl group, optionally substituted C6-C30 aryl group or optionally substituted C3-C30 heteroaryl group; L1 and L2 are each independently single bond, optionally substituted C1-C30 alkylene group, optionally substituted C6-C3 arylene group or optionally substituted C3-C30 heteroarylene group; Ar1 and Ar2 are each independently optionally substituted C6-C30 aryl group or optionally substituted C3-C30 heteroaryl group; p and q are each independently an integer from 1 to 5; and m and n are each independently an integer from 0 to 4.
