wherein, in Chemical Formula 1,
Ar is a substituted or unsubstituted C6 to C30 aromatic ring, a substituted or unsubstituted C3 to C30 heteroaromatic ring, or a combination thereof,
X1 is O, S, Se, Te, S(═O), S(═O2), NRa, CRbRc, SiRdRe, GeRfRg, CRh═CRi, or CRhh═CRii, wherein Ra, Rb, Rc, Rd, Re, Rf, Rg, Rh, and Ri are independently hydrogen, deuterium, a C1 to C30 alkyl group, a C1 to C30 haloalkyl group, a C6 to C30 aryl group, a C6 to C30 aryloxy group, a C3 to C30 heteroaryl group, a halogen, a cyano group, or a combination thereof, Rhh and Rii are independently (CH)w where w is a positive integer or at least one heteroatom of O, N, S, Se, or Te, and Rhh and Rii are linked to each other to form an aromatic ring or a heteroaromatic ring,
X2 is O, S, Se, Te, C, CRx—CRy, CRxx—CRyy, S(═O) or S(═O2), wherein Rx and Ry are independently hydrogen, deuterium, a C1 to C30 alkyl group, a C1 to C30 haloalkyl group, a C6 to C30 aryl group, a C6 to C30 aryloxy group, a C3 to C30 heteroaryl group, a halogen, a cyano group, or a combination thereof, Rxx and Ryy are independently (CH)v where v is a positive integer or at least one heteroatom of O, N, S, Se, or Te, and Rxx and Ryy are linked to each other to form an aromatic ring or a heteroaromatic ring,
Ar1 and Ar2 are independently a heteroarene group including at least one heteroatom of O, S, Se, or Te,
Ar3 and Ar4 are independently a substituted or unsubstituted C6 to C30 arene group, a substituted or unsubstituted C3 to C30 heteroarene group, or a condensed ring group thereof,
R1 and R2 are independently hydrogen, deuterium, a halogen, a cyano group, a nitro group, a hydroxyl group, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C1 to C10 alkoxy group, a substituted or unsubstituted C6 to C10 aryl group, or a substituted or unsubstituted C3 to C10 heteroaryl group, and
L1 and L2 are independently a single bond, —O—, —S—, —Se—, —Te—, —N═, —NRa—, —SiRbRc—, —GeRdRe—, —(CRfRg)n—, or —(C(Rh)═C(Ri))—, wherein Ra, Rb, Rc, Rd, Re, Rf, Rg, Rh, and Ri are independently hydrogen, deuterium, a halogen, a cyano group, a substituted or unsubstituted C1 to C10 alkyl group, or a substituted or unsubstituted C6 to C10 aryl group, wherein Rb and Rc, Rd and Re, Rf and Rg, or Rh and Ri are independently present or are linked to each other to form a separate ring, and n of —(CRfRg)n— is an integer of 1 or 2.
