Abstract: Provided are a novel compound and an organic electronic device using the same. The novel compound is represented by Formula (I): wherein n1, n2, m1, m2 and m3 are each an integer, the sum of n1 and n2 is 2 or 3; L1, L2 and L3 are each an arylene group; R1 and R2 are each selected from the group consisting of: H, D, an alkyl group, and an aryl group; G is selected from the group consisting of: H, D, —N(Z3)(Z4) group, an alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, a heterocycloalkyl group, an aryl group, and a heteroaryl group; and Z1 to Z4 are each selected from the group consisting of: an alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, a heterocycloalkyl group, an aryl group, and a heteroaryl group.

Abstract: An organic light-emitting diode (OLED) and a white OLED are provided. The OLED sequentially includes an anode, an emission layer, an electron transport layer, and a cathode. The emission layer includes a triplet-triplet annihilation (TTA) material and a donor material. The doubled triplet energy of the TTA material is greater than the singlet energy of the TTA material. The donor material is disposed between the anode and the TTA material and has a second singlet energy and a second triplet energy. A sensitizer is doped in the emission layer or formed between the TTA material and the donor material when a voltage is applied. The sensitizer has a third singlet energy and a third triplet energy. The third singlet energy and the third triplet energy are both smaller than the second singlet energy.
