Preorganized structures suitable for anion binding were prepared by introducing dipyrrolyldiketone BF complexes as acyclic anion-responsive π-electronic molecules into macrocycles. Pyrrole-inverted conformations, which typically present low stability in the case of acyclic derivatives, were obtained by covalent linkages through ring-closing olefin metathesis, exhibiting extremely high affinity for different anions.
通过将二吡咯二酮 BF 配合物作为非环阴离子响应π-电子分子引入大环中，制备了适合阴离子结合的预组织结构。通过闭环烯烃复分解反应通过共价键连接获得了通常在非环衍生物中稳定性较低的吡咯反转构象，对不同阴离子表现出极高的亲和力。
