Abstract
An organic photoelectric device may include an anode and a cathode configured to face each other, and an active layer between the anode and cathode, wherein the active layer includes a quinacridone derivative and a thiophene derivative having a cyanovinyl group.
Claims21
An organic photoelectric device, comprising:
- an anode and a cathode configured to face each other;
- and
- an active layer between the anode and cathode, the active layer including a quinacridone derivative represented by the following Chemical Formula 1 and a thiophene derivative having a cyanovinyl group:
- wherein, in Chemical Formula 1,
- each of R1 and R2 are independently one of hydrogen, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C3 to C30 heteroaryl group, and a combination thereof, and
- each of X1 and X2 are independently one of hydrogen and a substituted or unsubstituted C3 to C30 heterocyclic aromatic group, at least one of X1 and X2 being a substituted or unsubstituted C3 to C30 heterocyclic aromatic group.
