Three cationic iridium (III) complexes, [(ppy)₂Ir(4-FPhBIAN)]PF₆ (Ir1), [(ppy)₂Ir(3,4-F,FPhBIAN)]PF₆ (Ir2), [(ppy)₂Ir(4-CF₃PhBIAN)]PF₆ (Ir3) were synthesized from 2-phenylpyridine (Hppy) as cyclometalating ligand and N,N′-bis(aryl)acenaphthene as ancillary ligand. All the complexes were characterized by FT-IR, ¹H, ¹³C and ¹⁹F NMR spectroscopies, and elemental analysis. The molecular structures of the complexes were determined by X-ray crystallography. These complexes were crystalized as greenish-black needles in the triclinic P1 space group for complexes Ir1 and Ir3, while Ir2 was crystalized in the orthorhombic P2₁2₁2₁ space group. Electrochemical properties were studied by cyclic voltammetry analysis. All the complexes showed quasi-reversible oxidation and reduction peaks, and reversibility increased by scan rate. Electronic properties were studied by UV-visible spectroscopy, and intense absorption band below 300 nm was obtained compared to intense absorption bands between 300 ~ 530 nm. Density functional theory (DFT) calculations were employed to get better understanding of electrochemical properties.

三种阳离子铱（III）络合物，[（PPY）₂的Ir（4-FPhBIAN）] PF ₆（IR1），[（PPY）₂的Ir（3,4--F，FPhBIAN）] PF ₆（亮点Ir2），[（ ppy) ₂ Ir(4-CF ₃ PhBIAN)]PF ₆ ( Ir3 ) 由 2-苯基吡啶 (Hppy) 作为环金属化配体和 N,N'-双（芳基）苊作为辅助配体合成。所有配合物均通过 FT-IR、¹ H、¹³ C 和¹⁹F NMR光谱和元素分析。配合物的分子结构由 X 射线晶体学确定。这些配合物在配合物Ir1和Ir3的三斜P1空间群中结晶为绿黑色针状，而Ir2在正交P2 ₁ 2 ₁ 2 _{1 中}结晶空间群。通过循环伏安法分析来研究电化学性质。所有配合物均表现出准可逆的氧化和还原峰，可逆性随扫描速率的增加而增加。通过紫外-可见光谱研究了电子特性，与300~530 nm之间的强吸收带相比，获得了300 nm以下的强吸收带。采用密度泛函理论 (DFT) 计算来更好地了解电化学性质。
