包含一种以上客体分子的包合物结构是难以捉摸的，因为限制会改变它们的分子特性。我们报告了包含两个 γ-环糊精和两个 [Cu(2-吡啶甲醇)(2-吡啶甲醇)]PF6 单元的包合物的固态表征。量子计算表明发生了碎片间电荷转移。受限的 Cu 片段和未包含的“直链 [Cu(2-吡啶甲醇)(2-吡啶甲醇)]PF6”表现出不同的特性。
Inclusion structures incorporating more than one guest molecule are elusive because confinement alters their molecular properties. We report the solid-state characterization of an inclusion complex comprising two γ-cyclodextrins and two [Cu(2-pyridinemethanolate)(2-pyridinemethanol)]PF6 units. Quantum calculation reveals that interfragment charge transfer occurs. The confined Cu fragment and the unincluded “linear chain [Cu(2-pyridinemethanolate)(2-pyridinemethanol)]PF6” exhibit different properties.
