The arene iridium complexes [(η⁵-C₅R₅)M(η⁶-PhX)](SbF₆)₂ (1a: R = H, X = CH=CHPh; 1b: R = Me, X = CH=CHPh; 2: R = Me, X = C≡CPh; 3: R = Me, X = 4-Me-1H-isochromen-1-one) were synthesized by the reactions of the halides [CpIrI₂]_n or [Cp*IrCl₂]₂ with trans-stilbene, tolan and 3-phenyl-4-methyl-1H-isochromen-1-one in the presence of AgSbF₆. They have proved to be stable towards the arene replacement with nucleophiles (such as acetonitrile, water and KI). The structures of 1b(SbF₆)₂ and 3(SbF₆)₂ were determined by X-ray diffraction. The experimental and DFT calculation data showed that the coordination of trans-stilbene and 3-phenyl-4-methyl-1H-isochromen-1-one with the Cp*Ir-moiety leads to the fluorescence quenching due to the intramolecular charge transfer from the ligand to iridium.

芳烃铱络合物[（η ⁵ -C ₅ - [R ₅）M（η ⁶ -PhX）]（SBF ₆）₂（1A：R = H，X = CH = CHPh配合;图1b：R = Me中，X = CH = CHPh；2：R ＝ Me，X ＝ C ＝ CPh；3：R ＝ Me，X ＝ 4-Me-1H-异色素_n -1-one）是通过卤化物[CpIrI ₂ ] _n或[Cp在AgSbF ₆存在下，用反式-苯乙烯，甲苯基和3-苯基-4-甲基-1H-异色素n-1-酮合成* IrCl ₂ ] ₂。事实证明，它们对于用亲核试剂（如乙腈，水和KI）替代芳烃是稳定的。所述的结构1B（SBF ₆）₂和3（SBF ₆）₂，通过X射线衍射来确定。实验和DFT计算数据表明，反式-1,2-苯乙烯和3-苯基-4-甲基-1H-异色素n-1-one与Cp * Ir部分的配位导致分子内电荷从Cp * Ir转移而导致荧光猝灭。铱的配体
