Abstract
Novel compounds useful as hosts in OLEDs having Formula I
Claims15
A compound of Formula I
- wherein Z1 to Z13 are each independently C or N;
- wherein each RA, RB, RC, and RD independently represents mono to a maximum possible number of substitutions, or no substitution;
- wherein RA, RB, 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.
