摘要

制备了两种具有偕胺吡咯副臂的新型金刚烷阴离子受体，并通过紫外/可见光谱研究了它们在DMSO溶液中与TBA盐(Cl -、AcO -和H2PO4 -)的阴离子结合能力。在计算了受体-阴离子配合物的相应缔合常数后，很明显只有一个氨基吡咯侧臂参与络合。利用计算工具对这些实验结果进行了合理化，并提出了结合模式。除了发现1:1的化学计量外，我们还发现所研究的受体与氧阴离子(H2PO4 -和AcO -)的结合比球形卤素阴离子(Cl -)更强。

Synthesis and Anion Binding Assessment of Novel Adamantane Amidopyrroles

Two new adamantane anion receptors with amidopyrrole side arms were prepared and their anion binding ability in DMSO solutions with TBA salts (Cl–, AcO– and H2PO4–) was investigated by UV/Vis spectroscopy. After calculating the corresponding association constants of receptor-anion complexes, it became apparent that only one amidopyrrole side arm was engaged in complexation. These experimental findings were rationalized using computational tools and the binding mode was proposed. In addition to the found 1 : 1 stoichiometry, we showed that the studied receptors bind oxo-anions (H2PO4– and AcO–) more strongly than spherical halogenide (Cl–) anions.
