More Information
Summary:The present invention provides a novel phosphorescent heteroleptic iridium complex with phenylpyridine and dibenzo-containing ligands. Alkyl substitution at specific positions in the ligand results in compounds with improved OLED properties, including saturated green emission. A number of hole injection materials, hole transport materials, host materials, electron transport and electron injection materials can be used in OLEDs in addition to and/or in combination with the materials disclosed in the present invention. 본 발명은 페닐피리딘 및 디벤조-함유 리간드를 갖는 신규한 인광 헤테로렙틱 이리듐 착물을 제공한다. 리간드에서 특정 위치에서의 알킬 치환은 포화 녹색 방출을 비롯한 개선된 OLED 성질을 갖는 화합물을 생성한다.
