<p>A metal complex having a structure represented by the following formula (1). (1) (X1 and X2 each independently represents carbon or nitrogen; the bonds represented by (AAA) and (BBB) are a single bond or double bond; M represents a transition metal; the angle between the plane including the structure represented by (CCC) and the plane including the structure represented by (DDD) is 9-16‹, and in the highest occupied molecular orbital of the metal complex, the value obtained by dividing the proportion of the sum of the squares of the orbital coefficients for orbit d, which constitutes the outermost shell, of the metal atom M to the sum of the squares of all atomic orbital coefficients by the energy difference of the metal complex, S1-T1, between the minimum singlet excitation energy, S1, and the minimum triplet excitation energy, T1, is 200-600 %/eV.) ® KIPO & WIPO 2009</p> |
