WIPO Patent Application WO/2023/136295

A1

One purpose of the present invention is to provide a compound which is suitable for use as a material for a capping layer in an organic EL element, has a high refractive index in a wavelength range from 450 nm to 750 nm, and has a low extinction coefficient. Another purpose of the present invention is to provide an organic EL element having an improved light extraction efficiency due to use of the compound.　The present invention is a pyrimidine compound represented by general formula (1). (In formula (1), Ar1 to Ar3 may be the same as or different from one another and each independently represent a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic ring group or the like; L1 to L3 may be the same as or different from one another and each independently represent a single bond, a substituted or unsubstituted bivalent aromatic hydrocarbon group or the like; and p, q and r may be the same as or different from one another and each independently represent an integer of 1 to 2; in which at least one of Ar1 to Ar3 represents an aromatic heterocyclic ring group such as a substituted or unsubstituted benzoxazolyl group.)
