, p. 868 - 873 (2016)
A new donor moiety, 7,7,13,13-tetramethyl-7,13-dihydro-5H-indeno[1,2-b]acridine (IAc), was developed to control the highest occupied molecular orbital (HOMO) dispersion of thermally activated delayed fluorescent (TADF) emitters. The IAc unit expanded the HOMO dispersion of the emitters and increased the quantum efficiency of the TADF devices up to 20.9 %.

Paragraph 0186-0189, (2021/06/02)
The invention belongs to the technical field of organic materials, and provides a nitrogen-containing compound, and an organic electroluminescent device and an electronic device using the same. The nitrogen-containing compound has a structure as shown in a formula I, wherein X1, X2 and X3 are respectively and independently selected from N or CH, and at least one of X1, X2 and X3 is N. When the nitrogen-containing compound is used in the organic electroluminescent device, the performance of the device can be improved.
Electron transporting and hole blocking organic material and application thereof in thin-film light-emitting diode
-
Paragraph 0005, (2020/11/02)
The invention provides an electron transporting and hole blocking material with an A-D-A link structure as a core. The material is applied to a thin-film semiconductor light-emitting diode, for example, an organic light-emitting diode and a quantum dot thin-film light-emitting diode; and the molecule of the material takes bipolar carbazole and a derivative group thereof as electron donating centers, so a relatively high triplet state energy level can be maintained to ensure exciton blocking capability.
