Claims38
An aryl-substituted anthracene compound having Formula I:
- wherein:
- R1 through R8 are the same or different at each occurrence and are selected from the group consisting of H, D, alkyl, alkoxy, aryl, aryloxy, siloxane, and silyl;
- Ar1 and Ar2 are the same or different and are selected from the group consisting of aryl groups;
- and
- Ar3 and Ar4 are the same or different and are selected from the group consisting of H, D, and aryl groups;
- wherein the compound has at least eight D.
An organic electronic device comprising a first electrical contact layer, a second electrical contact layer, and at least one active layer therebetween, wherein the active layer comprises an aryl-substituted anthracene compound having Formula I:
- wherein:
- R1 through R8 are the same or different at each occurrence and are selected from the group consisting of H, D, alkyl, alkoxy, aryl, aryloxy, siloxane, and silyl;
- Ar1 and Ar2 are the same or different and are selected from the group consisting of aryl groups;
- and
- Ar3 and Ar4 are the same or different and are selected from the group consisting of H, D, and aryl groups;
- wherein the compound has at least eight D.
An aryl-substituted anthracene compound having Formula I:
- wherein:
- R1 through R8 are each D;
- Ar1 and Ar2 are the same or different and are a hydrocarbon aryl;
- and
