enhancement of the binding between halide anions and a Lewis acidic uranyl–salophen receptor has been achieved by the introduction of pendant electron‐deficient arene units into the receptor skeleton. The association and the occurrence of the elusive anion–π interaction with halide anions (as tetrabutylammonium salts) have been demonstrated in solution and in the solid state, providing unambiguous evidence
通过将缺乏电子的侧链芳烃单元引入受体骨架,可以增强卤化物阴离子与路易斯酸性尿嘧啶-salophen受体之间的结合。在溶液和固态中已经证明了阴离子与卤素阴离子(如四丁基铵盐)的难以捉摸的缔合和相互作用,这为负责阴离子结合的协同相互作用的相互作用提供了明确的证据。
