摘要:
An organic electroluminescence element that uses a compound expressed by the following general formula has low inter-molecular interaction and high orientation during vapor deposition, and by using compounds that are resistant to aggregation, luminous efficiency is high, and there is little change in chromaticity accompanying drive deterioration (either V1 or W1 and either V2 or W2 form rings, the rings formed by V1 and V2 are six-membered rings, and the rings formed by W1 and W2 are five-membered rings; A2 to A4 and A6 to A8 represent CRZ or N, and RZ represents a hydrogen atom or a substituent; and R2, R3, R7, and R8 represent a hydrogen atom, an alkyl group, an aryl group, a heteroaryl group, a fluorine atom, a hydrogen atom [sic], or a deuterium atom.).
