Title:
金属錯体およびそれを用いた発光素子
Document Type and Number:
Japanese Patent JP6555130
Kind Code:
B2
Abstract:
A metal complex represented by the formula (1):
[wherein,
M represents an iridium atom or a platinum atom.
n 1 represents 1, 2 or 3. n 2 represents 0, 1 or 2.
E 1 to E 4 represent a nitrogen atom or a carbon atom.
R 1 to R 10 represent a hydrogen atom, an alkyl group, a cycloalkyl group, an alkoxy group, a cycloalkoxy group, an aryl group, an aryloxy group, a monovalent heterocyclic group or a halogen atom. At least one selected from the group consisting of R 1 to R 4 is a group represented by the formula (D-A) or (D-B).
X a and X b represent a direct bond, an oxygen atom, a sulfur atom, -C(= O)-, -CR Xa 2 - or -NR Xa -. R Xa represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group. At least one of X a and X b is an oxygen atom, a sulfur atom, -C(= O)-, -CR Xa 2 - or -NR Xa -.
A 1 -G 1 -A 2 represents an anionic bidentate ligand, and G 1 represents an atomic group constituting a bidentate ligand together with A 1 and A 2 . A 1 and A 2 each independently represent a carbon atom, an oxygen atom or a nitrogen atom.]
[wherein,
m DA1 to m DA7 represent an integer of 0 or more.
G DA represents an aromatic hydrocarbon group or a heterocyclic group.
Ar DA1 to Ar DA7 represent an arylene group or a divalent heterocyclic group.
T DA represents an aryl group or a monovalent heterocyclic group.].
