| titleOfInvention | Green narrow-spectrum tricoordinate boron luminescent compound containing carbazole skeleton, preparation method and application thereof |
| abstract | A class of green light narrow-spectrum tri-coordinate boron luminescent compounds containing a carbazole skeleton, a preparation method and applications thereof in organic electroluminescent devices belong to the technical field of organic semiconductor light-emitting devices. The organic electroluminescent material of the present invention is centered on a green light narrow-spectrum tri-coordinated boron luminescent compound containing a carbazole skeleton, and a large steric hindrance group is introduced at the periphery of the entire molecular skeleton, which can open the molecular distance and effectively In addition, the moderately rigid and flexible conjugated structure can reduce the reorganization energy of the molecule, so that the structural deformation in the excited state of the molecule is small, Highly efficient organic electroluminescent compounds with narrow spectra (half width <30 nm) were obtained. The light-emitting layer of the organic electroluminescent device is prepared by the method of vacuum evaporation, thereby preparing the organic electroluminescent device with high efficiency and high color purity, which is applied in the full-color display technology. |
