Abstract

An organic electroluminescence device includes an anode, an emitting layer, and a cathode in this order. The emitting layer contains a compound, including a structure including a first partial structure of formula (3-100) and a second partial structure of formula (3-1A), mutually bonded in one molecule: In formula (3-100), Dto Dare each a deuterium atom, or one of Dto Dis a single bond to another atom/structure in the molecule, and remaining Dto Dare each a deuterium atom, and Ris a single bond bonded to the second partial structure. In formula (3-1A), one of Rto Ris a single bond bonded to the first partial structure, and remaining R301 to R306 not being bonded to the first partial structure are independently H, a substituent, or a single bond bonded to another atom/structure in the molecule.
