描述了六个新的自组装的超分子含As和Sb的配体的合成和X射线晶体结构。在先前报道的As 2 L 3和Sb 2 L 3配体的背景下进行的分析表明,配体几何形状的细微差异会导致复合物的螺旋度和组装的复合物中金属配位的立体化学存在显着差异。另外,描述了一种新的合成路线,该路线涉及将反应物暴露于真空中以帮助促进自组装。

Disclosed herein is a novel method for preparing cyclophanes, comprising forming a disulfide cyclophane by contacting a linker moiety which includes two or more thiol groups, with a metal salt and an oxidant. The disulfide cyclophane is then desulfurized to form a thiacyclophane comprising thioether bridges. This thiacyclophane optionally may be further desulfurized to form an unsaturated hydrocarbon cyclophane, which can then be reduced to form a saturated hydrocarbon cyclophane. The various cyclophanes can be synthesized in a ring form, such as a dimer, trimer or tetramer etc., or they can be synthesized in a tetrahedral or larger structure. Also disclosed are novel cyclophanes formed by the disclosed method.

The syntheses and X-ray crystal structures of six new self-assembled supramolecular As and Sb-containing cryptands are described. Analysis in the context of previously reported As2L3 and Sb2L3 cryptands reveals that small differences in ligand geometries result in significant differences in the helicity of the complexes and the stereochemistry of the metal coordination within the assembled complexes
