Paragraph 0049; 0056-0059, (2021/03/24)
The invention relates to dimethyl anthracene organic compounds and an application thereof to an OLED (organic light emitting diode) device. The structure of the compounds is that dimethyl anthracene is linked with a carbazole ring structure or a benzo six-membered ring structure through C-C bonds, the chemical stability of the material is improved and exposure of branch group active positions is avoided through linking of the C-C bonds, and the whole molecule is a larger rigid structure and has high triplet state energy level (T1); the compounds have large steric hindrance, cannot be rotated easily and have more stable stereoscopic space structure and thus have higher glass transition temperature and molecular heat stability. Besides, the HOMO and LUMO distribution positions of the compounds are separated, so that the compounds have proper HOMO and LUMO energy levels. Thus, the compounds can effectively improve the luminous efficiency and prolong the service life of the device effectively after being applied to the OLED device.

Paragraph 0046; 0050; 0052; 0053, (2018/03/06)
The invention relates to a dimethyl anthracene organic compound, and application thereof on an organic light-emitting device. A structure of the compound is characterized in that dimethyl anthracene is connected with a carbazole parallel loop structure through a carbon-carbon bond; with the carbon-carbon bond connection, the chemical stability of the material is improved, and an active position ofa branch perssad is prevented from being exposed; in addition, the whole molecule is of a larger rigid structure, has a high triplet state energy level (T1), and is large in steric hindrance, not easy to rotate, and more stable in three-dimensional space structure, so that the compound has higher glass state temperature and molecular heat stability; in addition, distribution positions of HOMO andLUMO of the compound provided by the invention are separated, so that the compound has appropriate HOMO and LUMO energy levels; therefore, after the compound provided by the invention is applied to the OLED (Organic Light-emitting Diode) device, the light-emitting efficiency and the service life of the device can be effectively improved.
