Organic photoelectric device and image sensor

An organic photoelectric device comprising:

• a first electrode and a second electrode facing each other;
• and
• an active layer between the first electrode and the second electrode, the active layer including a compound represented by the following Chemical Formula 1 and a compound represented by the following Chemical Formula 2:
• 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, a substituted or unsubstituted C1 to C30 alkoxy group, and a combination thereof, and
• each of R3 to R12 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, a substituted or unsubstituted C1 to C30 alkoxy group, a halogen atom, a halogen-containing group, and a combination thereof,
• wherein, in Chemical Formula 2,
• each of Ra to Rl 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, a halogen atom, a halogen-containing group, and a combination thereof, and
• X is an anion.
