Abstract
An iridium complex which has a phenylpyridine bidentate ligand containing a group represented by the following general formula (A): (In the general formula (A), X represents a cyano group or a halogenated alkyl group. L represents a single bond or a divalent linking group. R represents a substituent. n represents an integer of 0 to 4. * represents a binding site to a phenylpyridine bidentate ligand.)
Claims20
A compound represented by the following General Formula (1)
- wherein R111 to R134 each independently represent a hydrogen atom or a substituent;
- at least two adjacent groups out of R112 to R114, R114 and R115, at least two adjacent groups out of R115 to R118, at least two adjacent groups out of R120 to R122, R122 and R123, at least two adjacent groups out of R123 to R126, at least two adjacent groups out of R128 to R130, R130 and R131, or at least two adjacent groups out of R131 to R134 may be bonded to each other to form a ring, provided that one of R127 to R134 comprises a group represented by the following General Formula (A), and the number of the groups out of R111 to R134 in General Formula (1) which comprises a group represented by General Formula (A) is 1:
- X represents a cyano group;
- L represents a single bond or a divalent linking group;
- n represents an integer of 0 to 4;
- * represents a binding site;
- and
- R represents a substituent, wherein when a plurality of R's are present, they may be the same as or different from each other;
- wherein the compound is heteroleptic.
