The present invention provides a micromolecular electron transport material based on pyridine and triazole, which is represented by the formula I, and an organic light-emitting diode using the micromolecular electron transport material. The micromolecular electron transport material of the present invention can improve the capacity of electron injection, transmitting and hole-blocking, thus can gain high E
T
and reduce the driving voltage of device.
