Benzodiazaborole derivatives and organic light-emitting diodes using the same

An organic light-emitting diode, comprising:

• a first electrode layer;
• a second electrode layer;
• and
• an organic luminescent unit disposed between the first electrode layer and the second electrode layer, wherein the organic luminescent unit comprises at least a benzodiazaborole derivative, and the benzodiazaborole derivative comprises a structure of the following General Formula (1),
• wherein R1 is selected from the group consisting of hydrogen atom, General Formula (2), General Formula (3) and General Formula (4), R2 is selected from the group consisting of hydrogen atom, General Formula (3) and General Formula (4), R1 and R2 are different and at least one of them is a hydrogen atom, R3 is General Formula (4) when R2 is General Formula (4), and R3 is a hydrogen atom when R2 is a hydrogen atom or General Formula (3);
• and
• wherein R4 to R19 are independently selected from the group consisting of hydrogen atom, fluorine atom, cyano group, alkyl group, cycloalkyl group, alkoxy group, haloalkyl group, thioalkyl group, silyl group and alkenyl group.
