2-bis(diphenylphosphino)benzene (Ph-dppb), 4-pyrrolyl-1,2-bis(diphenylphosphino)benzene (Pr-dppb), and 4,5-dimethoxyl-1,2-bis(diphenylphosphino)benzene (OMe-dppb), were synthesized to coordinate with cuprous iodide (CuI), and compared with 1,2-bis(diphenylphosphino)benzene (dppb). Single crystal X-ray diffraction and elemental analysis experiments indicate that three binuclear CuI complexes with formulae of [Cu(μ2-I)Ph-dppb]2
三个新的双膦配体,4-苯基-1,2-双(二苯基膦基)苯(Ph-dppb),4-吡咯基-1,2-双(二苯基膦基)苯(Pr-dppb)和4,5-二甲氧基-合成了1,2-双(二苯基膦基)苯(OMe-dppb)以与碘化亚铜(CuI)配位,并与1,2-双(二苯基膦基)苯(dppb)进行了比较。单晶X射线衍射和元素分析实验表明与[Cu(上μ的公式三个双核配合物的CuI 2 -I)PH-DPPB] 2,[Cu(上μ 2 -I)镨DPPB] 2,和[铜(μ 2 -I)OME-DPPB] 2获得,这是相同的基准复合物[Cu(μ 2 -I)DPPB] 2。三个配合物显示出最大发射频带(λ最大在其中在取代的基团的电子效应而变化484-535 nm范围内)(即甲氧基,吡咯基,苯基)的[铜(μ 2 -I)DPPB] 2,并且在固态时从53%到90%的高光致发光量子产率(PLQY)。此外,配合物[铜(μ 2 -I)PH-DPPB]
