“D” in a structural formula of a compound of the present disclosure represents “deuterated”.
In the present disclosure, “aryl” refers to any functional group or substituent group derived from an aromatic carbon ring. An aryl group may be a monocyclic aryl group (e.g., phenyl) or a polycyclic aryl group. In other words, an aryl group may be a monocyclic aryl group, a fused aryl group, two or more monocyclic aryl groups linked by carbon-carbon bond conjugation, a monocyclic aryl group and a fused aryl group linked by carbon-carbon bond conjugation, or two or more fused aryl groups linked by carbon-carbon bond conjugation. That is, unless otherwise specified, two or more aromatic groups linked by carbon-carbon bond conjugation may also be regarded as an aryl group in the present disclosure. Among them, fused aryl groups may include, for example, bicyclic fused aryl groups (e.g., naphthyl), tricyclic fused aryl groups (e.g., phenanthryl, fluorenyl, anthryl) and the like. An aryl group does not contain heteroatoms such as B, N, O, S, P, Se, Si, etc. Examples of aryl may include, but are not limited to, phenyl, naphthyl, fluorenyl, spirodifluorenyl, anthryl, phenanthryl, biphenyl, terphenyl, triphenylene
In the present disclosure, “arylene” refers to a divalent group formed by further removing one or more hydrogen atoms from an aryl group.
In the present disclosure, “terphenyl” includes
