| titleOfInvention | A compound for phosphorescent host material and its application |
| abstract | The present invention relates to a compound for a phosphorescent host material, the structure of the compound is shown in formula (I); wherein, Ar 1 and Ar 2 are independently selected from phenyl, biphenyl or naphthyl. The invention provides a phosphorescent host compound containing an indole group. The structure of triazine is connected by benzoindole, the triplet state energy level of the molecule is improved, and the recombination area of excitons can be effectively widened, so that the excitons are uniform. distribution, avoid the recombination of carriers at the interface, and reduce the triplet-triplet quenching of excitons at high concentrations, thereby obtaining an excellent phosphorescent host material with a higher triplet state and a wider energy gap; the compound of the present invention It has a good application effect in OLED devices, and also has a good industrialization prospect. |
