OG Complex Work Unit Chemistry
wherein, R2 to R9 are identical or different, and each is independently hydrogen or deuterium;
R1 and R10 are identical or different, and each is independently selected from hydrogen, deuterium, and group A, and only one of R1 and R10 is selected from group A, and the group A is selected from an aryl having 6 to 12 carbon atoms, and a deuterated aryl having 6 to 12 carbon atoms;
Ar1 and Ar2 are identical or different, and each is independently selected from a substituted or unsubstituted phenyl, a substituted or unsubstituted naphthyl, a substituted or unsubstituted biphenyl, a substituted or unsubstituted terphenyl, a substituted or unsubstituted phenanthryl, a substituted or unsubstituted anthryl, a substituted or unsubstituted fluorenyl, a substituted or unsubstituted dibenzofuranyl, a substituted or substituted dibenzothienyl, and a substituted or unsubstituted carbazolyl;
substituent(s) in Ar1 and Ar2 are each independently selected from deuterium, fluorine, cyano, methyl, ethyl, n-propyl, isopropyl, tert-butyl, phenyl, naphthyl, trideuteromethyl, trifluoromethyl, and trimethylsilyl; optionally, any two adjacent substituents form a benzene ring, or a fluorene ring;
each L is independently selected from a substituted or unsubstituted phenylene, a substituted or unsubstituted naphthylene, a substituted or unsubstituted biphenylene, a substituted or unsubstituted fluorenylene, a substituted or unsubstituted dibenzothienylene, a substituted or unsubstituted dibenzofuranylene, and a substituted or unsubstituted carbazolylene, n represents 1 or 2, and when n is 2, each L is identical or different;
substituent(s) in L are identical or different, and each is independently selected from deuterium, fluorine, cyano, methyl, ethyl, isopropyl, and tert-butyl;
