1. An organic photoelectronic 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 first compound represented by the following Chemical Formula 1 or 2: wherein, in the Chemical Formula 1 and 2, each of R1 to R12 are independently one of hydrogen and a monovalent organic group, R1 to R12 are independently present or are fused to each other to provide a ring, R13 is one of a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C3 to C30 heteroaryl group, a substituted or unsubstituted silyl group, and a combination thereof, and each of R14 and R15 are independently one of a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C3 to C30 heteroaryl group, and a combination thereof, and a ratio between a full width at half maximum (FWHM) of a light absorption curve depending on a wavelength of the first compound in a solution state and in a thin film state satisfies the following Relationship Equation 1:
FWHM2/FWHM1<2.5 [Relationship Equation 1] wherein, in the Relationship Equation 1, FWHM1 is the FWHM of the light absorption curve depending on the wavelength in the solution state, and FWHM2 is the FWHM of the light absorption curve depending on the wavelength in the thin film state. |
