Abstract
The present invention is generally directed to luminescent lanthanide compounds with imine ligands, and devices that are made with the lanthanide compounds.
Claims14
A lanthanide compound having Formula IV below:
- Ln(β-enolate)3(diimine) (IV)
- where:
- in Formula (IV):
- diimine has Formula II;
- in Formula II:
- R1 can be the same or different at each occurrence and is selected from alkyl, fluorinated alkyl, aryl, heteroalkyl, heteroaryl, -QR2, -QN(R2)2, X, or adjacent R1 groups can join to form 5-membered or 6-membered rings,
- R2 is alkyl or aryl,
- Q is a single bond, alkylene, arylene, or —C(O)—,
- X is Cl, F, Br, or —CN,
- alpha is an integer from 1 to 4,
- γ is an integer from 1 to 3, and
- δ is 0 or an integer from 1 to 3,
- with the provision that in Formula II there is at least one R1 group having a fluorine.
