Paragraph 0066-0068, (2020/08/09)
The invention provides an organic light-emitting material based on a donor-receptor structure of a benzo[c][1,2,5]thiadiazole-4-aldehyde group receptor and a 2-(benzo[c][1,2,5]thiadiazole-4-methylene)malononitrile receptor and application thereof. The organic light-emitting material is a receptor-donor separation system, wherein the receptor is benzo[c][1,2,5]thiadiazole-4-aldehyde or 2-(benzo[c][1,2,5]thiadiazole-4-methylene) malononitrile, and a donor is carbazole and a derivative or benzoxazine and the like. The lowest unoccupied molecular orbital (LUMO) in the material is located in the receptor, and the highest occupied molecular orbital (HOMO) in the material is located in the donor, so that the molecular orbital energy level of the luminescent material can be effectively regulated and controlled through electrical regulation of the receptor structure and the donor. By regulating and controlling the structure of the light-emitting material or the electron donating capability of the donor, the light-emitting color of material molecules can be conveniently regulated. The organic light-emitting material has the characteristic that the light-emitting color is easy to adjust, andcan be used as a light-emitting material for preparing an OLED device.

Paragraph 0146; 0147; 0150-0153, (2016/12/01)
According to the present invention, hole transport materials induce a substituent which turns an orientation angle to two phenylene groups of a biphenyldiamine partial structure, and an aryl group to two nitrogen atoms of the biphenyldiamine partial structure, thereby improving light emitting properties such as low driving voltage and high light emitting efficiency, and increasing thermal stability by raising rotational energy barrier of molecules and lifespan of a diode. The hole transport material is a biphenyldiamine derivative represented by chemical formula 1. Accordingly, the present invention can manufacture an organic light emitting diode (OLED) of high efficiency, low voltage, high brightness, and long lifespan by using the same.COPYRIGHT KIPO 2015
