  Synthesis of a Preorganized Hybrid Macrobicycle with Distinct Amide and Amine Clefts: Tetrahedral versus Spherical Anions Binding Studies

  摘要：

  A new C-3, symmetric amido-amine hybrid macrobicycle, L is synthesized toward anion recognition in its protonated states. L contains tri-amide and tetra-amine clefts separated by p-phenylene spacers. The solid-state structure of methanol-encapsulated L exhibits an overall cavity length of similar to 12.0 angstrom where the amide and amine -NH protons are converged toward the center of the respective cavities. Conformational analysis of L in solution is established by NOESY NMR. Anion binding of [H3L](3+) with spherical (Cl-, Br-, I-) and tetrahedral (ClO4-, SO42-) anions are carried out by isothermal titration calorimeter in dimethylsulfoxide. The association of halides with [H3L](3+) is endothermic and entropy driven. However, association of tetrahedral anions is exothermic in nature and both entropy- and enthalpy-driven. The overall association constants show.the"following order: HSO4- > Br- > Cl- approximate to ClO4-. Single crystal X-ray structures of ClO4- and Br- complexes of protonated L show encapsulation of ClO4- in the amide cleft of [H2L](2+) (complex 1) and encapsulation of Br- in the ammonium cleft of [H3L](3+) (complex 2). Further, preorganization of L toward encapsulation of spherical and tetrahedral anions is established by comparing its amide, amine, and overall cavity dimensions with 1 and 2.
