- R is the same or different at each occurrence and is independently selected from the group consisting of hydrogen, alkyl, aryl, alkenyl, and alkynyl;
- R1 through R6 are the same or different and are independently selected from the group consisting of hydrogen, alkyl, aryl, halogen, hydroxyl, aryloxy, alkoxy, alkenyl, alkynyl, amino, alkylthio, phosphino, silyl, —COR, —COOK, —PO3R2, —OPO3R2, and CN,
- and wherein at least one of R1 through R6 is diarylamino and at least one of R2 and R4 is selected from the group consisting of alkyl, aryl, and diarylamino.
An organic electronic device comprising a first electrical contact, a second electrical contact and an electroactive layer therebetween, the electroactive layer comprising an electroactive material selected from the group consisting of a compound having Formula I:
- wherein:
- Q is the same or different at each occurrence and is independently selected from the group consisting of O, S, SO, SO2, Se, Te, NR, BR, PR, PO, PO2, and SiR2;
- R is the same or different at each occurrence and is independently selected from the group consisting of hydrogen, alkyl, aryl, alkenyl, and alkynyl;
