[摘要]：We describe the prepn. of a helicate contg. four closely spaced, linearly arrayed copper(I) ions. This product may be prepd. either directly by mixing copper(I) with a set of precursor amine and aldehyde helicate upon addn. of 1,2-phenylenediamine. A notable feature of this helicate is that its length is not limited by the lengths of its precursor subcomponents: each of the two ligands wrapped around the four copper(I) centers contains one diamine, two dialdehyde, and two monoamine residues. This work thus paves the way for the prepn. of longer oligo- and polymeric structures. DFT calcns. and electrochem. measurements indicate a high degree of electronic delocalization among the metal ions forming the cores of the structures described herein, which may therefore be described as "mol. wires".
