Abstract
A method for fabricating an OLED by preparing phosphorescent metal complexes in situ is provided. In particular, the method simultaneously synthesizes and deposits copper (I) complexes in an organic light emitting device. Devices comprising such complexes may provide improved photoluminescent and electroluminescent properties.
Claims20
A method, comprising:
- co-depositing one or more metal complexes having the formula MXn and one or more ligands by thermal vacuum depositing from two different heating sources to form a film comprising a phosphorescent complex over a substrate,
- wherein M is a transition metal or lanthanide;
- wherein X is alkyl, aryl, F, Cl, Br, I, SCN, OCN, CN, OR, and SR or combinations thereof;
- wherein ft is alkyl or aryl;
- wherein n is 1-10;
- wherein each ligand is independently a mono-, di-, tri- or polydentate ligand;
- and
- wherein the co-depositing step forms in-situ a phosphorescent complex comprising two to six of the metal complexes having the formula MXn and the one or more ligands.
