Abstract
The present invention includes novel compounds containing heterocycles or azaheterocycles and fused phenylene or aza and cyano substituted variants thereof. These compounds may be useful as host materials for phosphorescent electroluminescent devices. In some embodiments, the invention includes compounds of Formula I:
Claims19
A compound of Formula I
- wherein T1 to T20 are independently selected from the group consisting of CRT and N, and W1 to W6 are independently selected from the group consisting of CRW and N, wherein there is no more than two N in each 6-member aromatic ring;
- each RT and each RW is independently selected from the group consisting of hydrogen, deuterium, halogen, alkyl, deuterated alkyl, cycloalkyl, deuterated cycloalkyl, heteroalkyl, deuterated heteroalkyl, arylalkyl, deuterated arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, pyridine, pyrimidine, pyrazine, triazine, nitrile, isonitrile, benzonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
- optionally, any two adjacent RT can join to form a ring, or an RW can join with a proximate RT to form a 5-membered ring,
- with the proviso that when each of W3, W4, W5 and W6 are CRW, then at most one of these RW are aryl, heteroaryl or silyl.

- wherein T1 to T20 are independently selected from the group consisting of CRT and N, and W1 to W6 are independently selected from the group consisting of CRW and N, wherein there is no more than two N in each 6-member aromatic ring;
- each RT and each RW is independently selected from the group consisting of hydrogen, deuterium, halogen, alkyl, deuterated alkyl, cycloalkyl, deuterated cycloalkyl, heteroalkyl, deuterated heteroalkyl, arylalkyl, deuterated arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, pyridine, pyrimidine, pyrazine, triazine, nitrile, isonitrile, benzonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
- optionally, any two adjacent RT can join to form a ring, or an RW can join with a proximate RT to form a 5-membered ring,
- with the proviso that when each of W3, W4, W5 and W6 are CRW, then at most one of these RW are aryl, heteroaryl or silyl.
