    摘要： Pyrimidine derivatives of the present invention are represented by the following general formula (1), wherein W, X, Y and Z are carbon atoms or nitrogen atoms under the condition that only any one is a nitrogen atom to which none of the groups R6 to R9 are bonded, A and B are single bonds, divalent aromatic hydrocarbon groups or divalent aromatic heterocyclic groups, Ar1 and Ar2 are monovalent aromatic hydrocarbon groups or monovalent aromatic heterocyclic groups, and R1 to R9 are hydrogen atoms, deuterium atoms, fluorine atoms, chlorine atoms, cyano groups, alkyl groups having 1 to 6 carbon atoms, monovalent aromatic hydrocarbon groups or monovalent aromatic heterocyclic groups. The compound excels in electron injection/transporting capability, features high hole-blocking power and high stability in the form of a thin film, and can be favorably used as a material for producing highly efficient and durable organic EL devices.
