| titleOfInvention | Diphospha-containing heterocyclic cyclopentadiene fused ring organic electroluminescent compound and synthesis method thereof |
| abstract | The invention discloses a diphosphorus condensed ring-containing organic electroluminescent compound and a synthesis method thereof, belonging to the field of organic phosphorus electroluminescent materials. The compounds have a structural general formula shown in formula I, wherein E is O or S, and pi conjugated groups are phenyl or thiophene and the like. The compound can be used as a luminescent layer of an organic electroluminescent device to be applied to the electroluminescent device, and the luminescent performance of the device can be effectively changed by simply chemically modifying phosphorus atoms and changing pi-conjugated groups, so that the regulation and control from blue light to yellow light are realized; the compound has good thermal stability, almost no difference in the properties of cis-trans isomer devices, good charge injection and transmission capability, and can remarkably improve the efficiency and the service life of corresponding organic electroluminescent devices.
