Claims20
A compound of Formula I:
- Formula I;
- wherein M is Pd or Pt;
- wherein R1 is selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
- wherein L is , O, S, Se, NR, BR, CR′R″, SiR′R″, C═O, S═O, SO2;
- wherein RA, RC, and RD each independently represent mono to the maximum allowable substitution, or nor substitution;
- wherein R, R′, R″, RA, RC, and RD are each independently a hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
- and
- wherein any two substituents may be joined or fused together to form a ring.
