The invention discloses an electron transport compound and a synthetic method thereof, and an organic electroluminescent device, belonging to the field of chemical synthesis and photoelectric materials. The structural general formula of the electron transport compound is shown in the specification. In the formula, R1 and R2 are independently selected from the group consisting of hydrogen, a deuterium atom, halogen, a cyano group, a nitro group, a hydroxyl group, an amino group, a substituted or unsubstituted C1-C60 alkyl group, a C3-C60 cycloalkyl group, a C1-C60 heterocyclic group, a C1-C60 alkoxy group, a C1-C60 alkylamino group, a C3-C60 alkenylalkyl group, a C3-C60 alkynylalkyl group, a C6-C60 aryl group, a C6-C60 heteroaryl group, a C10-C60 condensed ring group and a C10-C60 spiro group; and R3 is independently one selected from the group consisting of hydrogen, a substituted or non-substituted C1-C30 alkyl group, a substituted or non-substituted C6-C30 aryl group, and a substituted or non-substituted C3-C30 heterocyclic group. The electron transport compound is used as a material for a light-emitting layer or an electron transport layer of the organic electroluminescent device, can remarkably reduce the driving voltage of the organic electroluminescent device, and improve the light-emitting efficiency and the service life of the organic electroluminescent device.
