First claim
Opening claim text (preview).
The invention claimed is: 1 . A compound represented by Chemical Formula 1: in Chemical Formula 1, Ar 1 is furan or thiophene fused with two adjacent rings, Ar 2 is benzene, benzofuran or benzothiophene fused with one adjacent ring, each n1 is independently an integer of 1 to 4, at least one of R 1 is benzofuranyl or benzothiophenyl, the rest are independently hydrogen, deuterium, halogen, cyano, a substituted or unsubstituted C 1-60 alkyl, a substituted or unsubstituted C 2-60 alkenyl, a substituted or unsubstituted C 2-60 alkynyl, a substituted or unsubstituted C 3-30 cycloalkyl, a substituted or unsubstituted C 6-60 aryl, or a substituted or unsubstituted C 2-60 heteroaryl containing one or more heteroatoms selected from N, O or S, and R 2 is hydrogen; deuterium; or a substituted or unsubstituted C 1-60 alkyl. 2 . The compound of claim 1 , wherein: the compound is represented by any one of Chemical Formulas 1-1 to 1-4: in Chemical Formulas 1-1 to 1-4, Ar 2 , n1, R 1 , and R 2 are as defined in claim 1 . 3 . The compound of claim 1 , wherein: at least one of R 1 is and the rest are independently hydrogen, deuterium, a substituted or unsubstituted C 1-60 alkyl, a substituted or unsubstituted C 6-60 aryl, or a substituted or unsubstituted C 2-60 heteroaryl containing one or more heteroatoms selected from N, O or S. 4 . The compound of claim 1 , wherein: at least one of R 1 is and the rest are independently hydrogen, deuterium, a C 3-10 alkyl, phenyl, dibenzofuranyl, or dibenzothiophenyl. 5 . The compound of claim 1 , wherein: at least one of R 1 is and the rest are independently hydrogen, deuterium, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tertbutyl, phenyl, dibenzofuranyl, or dibenzothiophenyl. 6 . The compound of claim 1 , wherein: R 2 is hydrogen, deuterium, or a C 1-4 alkyl. 7 . The compound of claim 1 , wherein: R 2 is hydrogen, deuterium, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, or tertbutyl. 8 . The compound of claim 1 , wherein: the compound is any one selected from the group consisting of:
