Abstract
There is provided an electroactive material having Formula I wherein: Q is the same or different at each occurrence and can be O, S, Se, Te, NR, SO, SO2, or SiR3; R is the same or different at each occurrence and can be hydrogen, alkyl, aryl, alkenyl, or alkynyl; and R1 through R6 are the same or different and can be hydrogen, alkyl, aryl, halogen, hydroxyl, aryloxy, alkoxy, alkenyl, alkynyl, amino, alkylthio, phosphino, silyl, —COR, —COOR, —PO3R2, —OPO3R2, or CN.
Claims9
An organic electronic device comprising a first electrical contact, a second electrical contact and an electroactive layer therebetween, the electroactive layer comprising a polymer having at least one monomeric unit having Formula III:
- wherein:
- Q is O
- R is the same or different at each occurrence and is independently selected from the group consisting of hydrogen, alkyl, aryl, alkenyl, and alkynyl;
- and
- R1 through R4 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, —COOR, —PO3R2, —OPO3R2, and CN;
- wherein the electroactive layer is a photoactive layer.
An organic electronic device comprising a first electrical contact, a second electrical contact and an electroactive layer therebetween, the electroactive layer comprising a polymer, wherein the polymer has Formula V:
- wherein:
- Ar is the same or different at each occurrence and is an aromatic unit;
- Q is O;
- 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 R4 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, —COOR, —PO3R2, —OPO3R2, and CN;
