| titleOfInvention | A high-efficiency dark blue fluorescent doping material and OLED organic electroluminescent device |
| abstract | A high-efficiency dark blue fluorescent doping material and an OLED organic electroluminescence device. The present invention discloses an organic electroluminescent compound and an organic electroluminescent device comprising the compound. The structural formula of the organic electroluminescent compound is shown in formula I: Such compounds can be used as organic electroluminescent materials. Due to the seven-membered ring formed by the combination of Ra, Rb and Z1, Z2, Z3 and Z4, Z5, Z6 through bridging, the seven-membered ring increases the material Molecules, rigidity and planarity can effectively improve the thermal stability of material molecules and increase the service life of materials. The introduction of the seven-membered ring improves the conjugation effect of material molecules, which can increase the electron cloud density of the conjugated system, thereby increasing the The luminous efficiency of material molecules. Experiments show that, compared with the prior art, the materials in the present invention have significantly improved lifespan and efficiency. |
