PROBLEM TO BE SOLVED: To provide heteroleptic iridium complexes useful as dopants in OLED devices.SOLUTION: The invention provides compounds including heteroleptic iridium complexes represented by formula II. (R1 to R6 are each independently H, D, cycloalkyl, deuterated cycloalkyl, alkyl, or deuterated alkyl; at least one of R1 to R6 is cycloalkyl, deuterated cycloalkyl, alkyl, or deuterated alkyl; R and R' are mono-, di-, tri- or tetra-substitution and are H, D, halogen, alkyl, aryl, or the like.)SELECTED DRAWING: None 【課題】ＯＬＥＤデバイスにおけるドーパントとして有用なヘテロレプティックイリジウム錯体の提供。【解決手段】式ＩＩで表されるヘテロプティックイリジウム錯体を含む化合物。（Ｒ１〜Ｒ６は各々独立にＨ、Ｄ、シクロアルキル、重水素化シクロアルキル、アルキル又は重水素化アルキル；Ｒ１〜Ｒ６の少なくとも１つは、シクロアルキル、重水素化シクロアルキル、アルキル又は重水素化アルキル；Ｒ及びＲ'は、モノ−、ジ−、トリ−、又はテトラ置換で、Ｈ、Ｄ、ハロゲン、アルキル、アリール等）【選択図】なし
