Cis-5,15-bis(3,5-trifluorometylphenyl)calix[4]pyrrole (1) forms stable 1/1 complexes with linear anions such as N3-, SCN‑ and NCO‑ with the highest affinity for NCO- anion in acetonitrile solution. Crystallization of receptor 1 with TBASCN and (TMA)2SO4 resulted in the formation of dimeric capsular assembly, {(TMA)2[12•(SCN)2]}, in which two thiocyanate anions are encapsulated. On the other hand, 1•OCN(TMA) and 1•N3(TMA) complexes form one dimensional columnar structure in the solid state.

Cis-5,15-双(3,5-三氟甲基苯基)杯[4]吡咯与线性阴离子的结合和阴离子封装的二聚体胶囊组装体的形成


Cis-5,15-双(3,5-三氟甲基苯基)杯[4]吡咯 (1) 与线性阴离子（例如 N3-、SCN- 和 NCO-）形成稳定的 1/1 复合物，对 NCO- 阴离子具有最高的亲和力乙腈溶液。受体1与TBASCN和(TMA)2SO4的结晶导致二聚体荚膜组装体的形成，{(TMA)2[12·(SCN)2]}，其中封装有两个硫氰酸根阴离子。另一方面，1•OCN(TMA)和1•N3(TMA)配合物在固态下形成一维柱状结构。
