Abstract
A furan-based hexaazamacrocycle encapsulates a sulfate anion in its cavity showing strong affinity and selectivity for sulfate in water over a wide range of inorganic anions. The DFT calculations demonstrate that the receptor provides binding sites as hydrogen bonding donors and electrostatic positive charges for the strong binding of sulfate.
摘要
一种基于呋喃的六氮杂大环化合物在其空腔中包封了一个硫酸根阴离子，在水中对硫酸根表现出对多种无机阴离子的强亲和力和选择性。密度泛函理论计算表明，该受体为硫酸根的强结合提供了作为氢键供体的结合位点和静电正电荷。
