Organometallic compounds comprising a germanium-containing substituent are provided. The compounds may be used in organic light emitting devices to provide improved device efficiency, line shape and lifetime. In particular, the compounds comprise a phenylquinoline or phenylisoquinoline ligand having a germanium-containing substituent on the quinoline or isoquinoline portion of the ligand. These compounds may be advantageously used as red emitters in the emissive layer of organic light emitting devices.
提供了含有锗取代基的有机金属化合物。这些化合物可用于有机发光器件,以提高器件效率、线形和寿命。具体来说,这些化合物包括在配体的喹啉或异喹啉部分上具有含锗取代基的苯基喹啉或苯基异喹啉配体。这些化合物可优势地用作有机发光器件发射层中的红色发射体。
