  • Manganese (II) complex, preparation method thereof, and use thereof in organic light emitting diodes
    Patent number: 11279721
    Abstract: The invention relates to a manganese (II) complex, its preparation method and use. The structure of the complex is (R1R2R3R4A)2[MnX4], wherein R1, R2, R3 and R4 are identical or different, independently selected from alkyl, aryl, or heteroaryl; said alkyl, aryl, or heteroaryl can be optionally substituted with a substituent, and the substituent is preferably alkyl, aryl or heteroaryl; A is N, P, or As; X is optionally F, Cl, Br, or I. The present invention also relates to an organic light emitting diode, its preparation method and use, wherein the manganese (II) complex of the invention is used as a dopant in the light-emitting layer. The prepared organic light emitting diode exhibits high electrical-to-optical conversion efficiency which can be used for flat-panel displays and illuminations.
