Compound having pyrimidine ring structure and organic electroluminescence device

Abstract

It is an object of the present invention to provide, as a material for organic EL device having high efficiency and high durability, an organic compound having excellent characteristics such as excellent electron injection/transport performance, hole blocking performance, and high stability in a film state, and an organic EL device having high efficiency and high durability, which is obtained by using this compound. A compound having a pyrimidine ring structure, the compound being represented by the following general formula (1). (In the formula, Arepresents a substituted or unsubstituted aromatic heterocyclic group. Arrepresents a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted fused polycyclic aromatic group. Arrepresents a deuterium atom, a trimethylsilyl group, a triphenylsilyl group, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted fused polycyclic aromatic group. m represents an integer of 1 to 3, n represents an integer of 0 to 2, and o represents an integer of 1 to 2. In a case where m is an integer of two or more, a plurality of Arbonded to the same pyrimidine ring may be the same or different from each other. In a case where n is an integer of two, a plurality of Arbonded to the same pyrimidine ring may be the same or different from each other. In a case where o is an integer of two, a plurality of Abonded to the same pyrimidine ring may be the same or different from each other. However, the sum of the integers of m, n, and o is 4 or less. Note that in a case where n is 0, Arrepresents a hydrogen atom.)
