Abstract
(EN)
Disclosed is a dibenzo heterocyclic compound, which has the structure as shown in formula (I). The dibenzo heterocyclic compound has a low LUMO energy level, can match well with an electron transport material, and is conducive to the injection and transport of electrons. The dibenzo heterocyclic compound has a good hole transport ability, and as a light-emitting layer material, same can balance the proportion of electrons to holes in a light-emitting layer to increase the probability of recombination, so as to improve the light emission efficiency of a device. By means of the spatial configuration of the dibenzo heterocyclic compound, the stacking of material molecules can be avoided so as to prevent intermolecular energy transfer leading to the production of high-energy excitons, thereby reducing the annihilation of excitons and suppressing efficiency roll-off. In addition, the dibenzo heterocyclic compound has a good thermal stability, and can achieve highly efficient and stable blue-light emission. Also disclosed is an organic electroluminescent device, at least one functional layer of which contains the above dibenzo heterocyclic compound, and by means of which a blue-light device having a high blue light emission efficiency and a low working voltage can be achieved.

L'invention concerne un composé dibenzo-hétérocyclique ayant une structure telle que représentée par la formule (I). Le composé dibenzo-hétérocyclique a un faible niveau d'énergie LUMO, peut bien correspondre avec un matériau de transport d'électrons, et est approprié à l'injection et au transport d'électrons. Le composé dibenzo-hétérocyclique a une bonne capacité de transport de trous, et est utile en tant que matériau de couche électroluminescente, ce qui permet d'équilibrer la proportion électrons/trous dans une couche électroluminescente pour augmenter la probabilité de recombinaison, de façon à améliorer l'efficacité d'émission de lumière d'un dispositif. La configuration spatiale du composé dibenzo-hétérocyclique, permet d’éviter l'empilement de molécules du matériau de façon à empêcher un transfert d'énergie intermoléculaire conduisant à la production d'excitons à haute énergie, ce qui permet de réduire l'annihilation des excitons et d'éviter la diminution de l'efficacité. De plus, le composé dibenzo-hétérocyclique a une bonne stabilité thermique, et peut obtenir une émission de lumière bleue hautement efficace et stable. L'invention concerne également un dispositif électroluminescent organique, dont au moins une couche fonctionnelle contient le composé dibenzo-hétérocyclique susmentionné, et grâce auquel un dispositif à lumière bleue ayant une efficacité d'émission de lumière bleue élevée et une faible tension de fonctionnement peut être produit.
