METAL COMPLEX, AND LIGHT-EMITTING ELEMENT INCLUDING SAME

摘要

The present invention provides a highly stable metal complex which is useful in the production of a light-emitting element exhibiting excellent longevity particularly with respect to the blue region. More specifically, the present invention provides a metal complex represented by formula (1) (in formula (1): M is a metal atom; Each R0 independently represents a divalent linking group; i and j each independently represent either 0 or 1; RP1, RP2, RP3, RP4, RP5, and RP6 each independently represent a hydrogen atom or the like, on condition that at least one of RP1, RP2, RP3, RP4, RP5, and RP6 is a dendron; m is an integer in the range of 1-3, n is an integer in the range of 0-2, and m+n equals either 2 or 3; and the moiety represented by formula (2) is a bidentate ligand (in formula (2), Rx and Ry are atoms bonded to the metal atom (M), each independently representing carbon atoms or the like)).
