Abstract
The present invention provides a metal complex containing a cation represented by [(MII)2(MI)2(LC)2(LB)4]2+ [in the aforementioned formula, MII is PtII or PdII, MI is H+, AuI, AgI, CuI, HgI, TlI or PbI, and LC and LB are ligands]. The metal complex of the present invention is useful as a light emitting material of an organic EL device.
Claims18
A metal complex containing a cation represented by the formula (C1)
- [(MII)2(MI)2(LC)2(LB)4]2+ (C1)
- in the formula (C1), MII is PtII or PdII,
- MI is H+, AuI, AgI, CuI, HgI, TlI or PbI,
- LC is a compound represented by any of the formula (LC-1)-the formula (LC-5), and
- LB is a monovalent anion represented by the formula (LB-1).
- in the formula (LC-1)-the formula (LC-5), R1-R34 are each independently a hydrogen atom, a halogen atom, an alkyl group optionally having substituent(s), or an aryl group optionally having substituent(s), or one or plural sets of the adjacent groups from R1-R34 form a hydrocarbon ring optionally having substituent(s) or a heterocyclic ring optionally having substituent(s),
- in the formula (LB-1), X1 is an alkyl group optionally having substituent(s), and X2 and X3 are each independently a hydrogen atom, a halogen atom, an alkyl group optionally having substituent(s), or an aryl group optionally having substituent(s).
