Abstract

A biphenyl-bridged bis(cyclen) cyclophane L containing two argentivorous Ag(I)-binding sites was synthesized, and its Ag(I)-binding behavior was investigated in the solid state and in solution. Single-crystal X-ray diffraction and spectroscopic studies showed a pronounced Ag(I)-induced conformational reorganization from an open free-ligand structure to a compact, helically wrapped di-Ag(I) complex, while NMR, CSI-MS, and equilibrium analysis showed that the mono-Ag(I) intermediate does not accumulate substantially. These results suggest that conformational reorganization accompanying the first Ag(I)-binding event may facilitate subsequent uptake of the second Ag(I) ion.

联苯桥接双（环）环烷：Ag(I)诱导的构象重组和连续的Ag(I)结合。

合成了一种含有两个银离子结合位点的联苯桥接双（环）环烷L，并对其在固态和溶液中的银离子结合行为进行了研究。单晶x射线衍射和光谱研究表明，Ag(I)诱导的构象重组从开放的自由配体结构转变为紧凑的螺旋包裹的双Ag(I)配合物，而核磁共振、CSI-MS和平衡分析表明，单Ag(I)中间体并没有大量积累。这些结果表明，伴随第一个Ag(I)结合事件的构象重组可能促进随后第二个Ag(I)离子的摄取。
