Abstract
The present invention includes novel organic materials comprising indolo[2,3-c]carbazole linked to an aromatic heterocycle via a carbazole linker. These materials may be useful as host materials for PHOLED devices.
Claims20
A compound of Formula I:
- wherein
- X1 to X23 are independently selected from carbon or nitrogen, wherein at least one of X19 to X23 is nitrogen, and there is no direct bond between X18 and X19 or X23;
- wherein if any of the X1 to X23 is carbon, then RA, RB, RC, RD, RE, and RF each independently represent mono to the maximum allowable substitution, or no substitution to each respective ring;
- RA, RB, RC, RD, RE, and RF are each independently selected from the group consisting of hydrogen, deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
- wherein at least one pair of two adjacent groups RA, RB, RC, RD, RE, and RF join to form a ring;
- Ar1 is a six-membered aromatic ring that is optionally substituted and/or Ar1 can join with X5 to form a ring;
- and
- optionally, X1 and X7 can join to form a ring.
