Abstract
The present disclosure provides coinage metal carbene emitters of Formula I; organic light emitting device (OLED) comprising an anode, a cathode, and an organic layer, disposed between the anode and the cathode, comprising a compound of Formula I; and consumer products comprising an OLED comprising a compound of Formula I:
Claims20
A compound represented by the following Formula I:
- wherein M1 is selected from the group consisting of Au(I), Ag(I), and Cu(I);
- L is a carbene coordinated to the metal M1;
- Z is a monoanionic ligand;
- E1 is an electron accepting group;
- n is an integer from 1 to the maximum allowable substitution on L, wherein when n is greater than 1, each E1 may be the same or different;
- E1, L, and Z may each be substituted with one or more substituents independently selected from the group consisting of hydrogen, deuterium, halogen, pseudohalogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, amide, hydroxyl, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, heteroalkynyl, aryl, heteroaryl, nitro, nitrile, isonitrile, sulfanyl, boryl, acyl, carboxylic acid, benzoyl, ether, ester, vinyl, ketone, sulfinyl, sulfonyl, cyano, phosphino, and combinations thereof;
- wherein any two adjacent substituents may together join to form a ring.
