METAL COMPLEXES WITH BORON-NITROGEN HETEROCYCLE CONTAINING LIGANDS FOR USE IN ORGANIC LIGHT EMITTING DEVICES |
摘要 |
Organic compounds comprising ligands containing a boron-nitrogen heterocycle are provided. The compounds comprise a ligand L coordinated to a central iridium metal atom. Ligand L is represented by compounds 1, 6, 7, 12, 25 and 28. In particular, the compound is a metal complex comprising a ligand containing an azaborine. The compounds may be used in organic light emitting devices to provide devices having improved photophysical and electronic properties. |
