significantly high oxidation potential (990 mV vs SCE), thus showing virtually no reactivity toward O2. On the other hand, the metal centers of the dinuclear and trinuclear copper(I) complexes, 3 and 4, exhibit a distorted trigonal planar geometry and a trigonal pyramidal geometry, respectively. In contrast to the mononuclear copper(I) complexes, these dinuclear and trinuclear copper(I) complexes reacted
新型配体Pye2(1,3,5-三乙基-2,4-双((N-苄基-N-(2-(吡啶-2-基)乙基)-)氨基甲基)苯),Pye3(1,3,5-三乙基-2,4,6-三((N-苄基-N-(2-(吡啶-2-基)乙基))氨基甲基)苯e),MePym2(1,3,5-三乙基-2,4-双((N-苄基-N-(6-甲基吡啶-2-基甲基))氨基甲基)苯)和MePym3(1,3,5已研究了-三乙基-2,4,6-三((N-苄基-N-(6-甲基吡啶-2-基甲基))氨基甲基)b烯)。通过将两个或三个吡啶基烷基胺金属结合位点连接到1,3,5-三乙苯间隔基上,可将配体设计为构建单核,二核和三核铜(I)配合物。因此,配体与[CuI(CH3CN)4] X(X = PF6,CF3SO3)或CuICl的反应产生了预期的单核铜(I)络合物[CuI(Pye2)(CF3SO3)](1)和[CuI( Pye3)](CF3SO3)(2),双核铜
