Abstract
Disclosed are a fullerene derivative including a substituent represented by Chemical Formula 1, and a photoelectric device, an image sensor, and an electronic device including the fullerene derivative. In Chemical Formula 1, X, Ar, and R1 to R3 are the same as defined in the detailed description.
Claims23
A fullerene derivative comprising:
- a substituent represented by Chemical Formula 1,
- wherein, in Chemical Formula 1,
- Ar is a C6 to C30 aromatic ring,
- X is one of O, S, Se, Te, SO, SO2, NRa, CRbRc, SiRdRe, or GeRfRg,
- R1 to R3 and Ra to Rg are independently one of hydrogen, deuterium, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C1 to C20 heteroalkyl group, a substituted or unsubstituted C2 to C20 alkenyl group, a substituted or unsubstituted C2 to C20 heteroalkenyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C3 to C30 heterocyclic group, a halogen, a cyano group, or a combination thereof, and
- * is a linking point with a fullerene core, and
- provided that when Ar is a benzene ring, Chemical Formula 1 is represented by Chemical Formula 2,
- wherein, in Chemical Formula 2,
- X and R1 to R3 are the same as defined in Chemical Formula 1, and
- at least two of R1 to R3 are independently a substituted or unsubstituted C3 to C20 branched alkyl group.
