Provided are an electron transport compound, which has a high electron transport efficiency and good film formation, prevents crystallization, and has less effect on a diode lifespan, and organic light emitting diodes using the same, which has high brightness, high efficiency, and long life. The electron transport compound has a structure represented by the following formula 1, wherein A1 and A2 are independently selected from the group consisting of substituted or unsubstituted aromatic groups, heterocyclic groups, and aliphatic groups. The substituted or unsubstituted A1 and A2 are selected from phenyl, biphenyl, pyridyl, naphthyl, quinoline, isoquinoline, fluorene, terphenyl, methyl, ethyl, propyl, isopropyl, halogen, phenanthroline, quinoxaline, terpyridine, amide, benzothiazolyl, bipyridyl, bisphenyl oxadiazolyl, and substituents thereof.
