Abstract
AbstractWe describe the preparation of a helicate containing four closely spaced, linearly arrayed copper(I) ions. This product may be prepared either directly by mixing copper(I) with a set of precursor amine and aldehyde subcomponents, or indirectly through the dimerization of a dicopper(I) helicate upon addition 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 preparation of longer oligo‐ and polymeric structures. DFT calculations and electrochemical 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 “molecular wires”.

- We expect the error to be largest for31 a4+because this molecule has the largest charge to size ratio and thus the greatest uncertainty in predicted solvation‐free energy. The predicted values for2 aare likely to be more quantitatively accurate than those for1 abecause2 ais larger by about a factor of two but oxidation increases its total molecular charge by only 50 rather than 100 %.
