Claim 14:
15. The compound of claim 14, wherein the compound is selected from the group consisting of compounds having the formula of Pt(LA′)(Ly) with the following structure:, wherein LA′ corresponds to the ligand of Formula IV, wherein Z1, Z2, and Z3 are each C;, wherein Z1, Z2, and Z3 are joined to a linking group selected from the group consisting of:, wherein RE represents zero, mono, or up to a maximum allowed number of substitutions to its associated ring;
wherein RE for each occurrence is independently a hydrogen or a substituent selected from the group consisting of the general substituents as defined herein;
wherein each Y can be the same or different and is independently selected from the group consisting of O, S, SO2, SO, Se, CR′R″, SiR′R″, GeR′R″, BR′, and NR′;, wherein Q is selected from the group consisting of CR′, SiR′, GeR′, B, and N;, wherein each R′ and R″ can be the same or different and is selected from the group consisting of hydrogen, deuterium, alkyl, cycloalkyl, aryl, heteroaryl, and combinations thereof; and, wherein any adjacent R′ or R″ groups can be linked,
wherein Ly is selected from the group consisting of the structures shown in the list below:, Ly

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

wherein R, RE, RF, and RG each represents zero, mono, or up to the maximum number of allowed substitutions to its associated ring; each R1, R2, R3, R4, R, RE, RF and RG are independently a hydrogen or a substituent selected from the group consisting of deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, boryl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acid, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; and two adjacent R1, R2, R3, R4, R, RE, RF and RG can be joined or fused to form a ring wherever chemically feasible.
