Claims27
A compound having Formula I:
- wherein:
- R1, R2, R3 and R4 are the same or different and are selected from the group consisting of H and alkyl, where R1 and R2 groups or R3 and R4 groups may be joined together to form a 5- or 6-membered aliphatic ring;
- R5 and R6 are the same or different and are selected from the group consisting of alkyl groups, m-phenyl, o-phenyl, p-phenyl, m-carbazolyl, and p-carbazolyl;
- R7 is the same or different at each occurrence and is selected from the group consisting of alkyl groups, phenyl, and biphenyl, or two adjacent R7 groups can join together to form a naphthyl group;
- a and b are the same or different and are an integer from 0-10;
- c and d are the same or different and are an integer from 1-3;
- f, g, h, and i, are the same or different at each occurrence and are an integer from 0-4;
- and
- e and j are the same or different at each occurrence and are an integer from 0-5.
A compound selected from E1 through E17.
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 a compound having Formula I:
- wherein:
- R1, R2, R3 and R4 are the same or different and are selected from the group consisting of H and alkyl, where R1 and R2 groups or R3 and R4 groups may be joined together to form a 5- or 6-membered aliphatic ring;
- R5 and R6 are the same or different and are selected from the group consisting of alkyl groups, m-phenyl, o-phenyl, p-phenyl, m-carbazolyl, and p-carbazolyl;
- R7 is the same or different at each occurrence and is selected from the group consisting of alkyl groups, phenyl, and biphenyl, or two adjacent R7 groups can join together to form a naphthyl group;
- a and b are the same or different and are an integer from 0-10;
- c and d are the same or different and are an integer from 1-3;
- f, g, h, and i, are the same or different at each occurrence and are an integer from 0-4;
- and
- e and j are the same or different at each occurrence and are an integer from 0-5.
