| titleOfInvention | Phosphorescent compound, preparation method thereof, and organic electroluminescent device comprising it |
| abstract | The invention discloses a phosphorescent compound, its preparation method and an organic electroluminescent device containing it, belonging to the technical field of chemistry and organic luminescent materials. The general structural formula of the phosphorescent compound is: In the formula, ring A can be connected with any two adjacent positions on the benzene ring to form a combined ring; ring A is independently represented as substituted or unsubstituted C6-C18 aryl, substituted or unsubstituted 3 At least one of member-18 membered heteroaryl, substituted or unsubstituted C3-C12 cycloalkyl; and ring A is monocyclic or polycyclic; L is substituted or unsubstituted C6-C30 aromatic At least one of radical, substituted or unsubstituted 3-18-membered heteroaryl; L is monocyclic or polycyclic, and L is not anthracene; n is selected as a natural number of 0-10. The phosphorescent compound provided by the invention, after being used in an organic electroluminescent device, can improve the luminous efficiency of the device and prolong the service life of the device. |
