氮原子上的取代（必要时通过高压 SNAr 反应）连接杂环芳烃的氮杂 18 冠 6 醚扩大了 Ag+ 潜在主体化合物的数量。通过液膜离子传输和离子萃取实验评估了新化合物与Ag+的络合。这些新主体化合物对于Ag+的结合位点的性质已经在DMF/D2O(4/1)中通过AgClO4的13C nmr滴定实验进行了评估。
Substitution on the nitrogen atom, where necessary by high‐pressure SNAr reactions, of aza‐18‐crown‐6 ethers linked to heterocyclic aromatics has extended the number of potential host compounds for Ag+. The complexation of Ag+by the new compounds has been evaluated by liquid membrane ion transport and ion extraction experiments. The nature of the binding sites of these new host compounds for Ag+has been assessed, in DMF/D2O (4/1), by13C nmr titration experiments with AgClO4.
