Abstract:
The ferrocene moiety with its well‐defined redox behavior and its substitution potential is ideally suited for the assembly of multinuclear complexes. Utilizing the “click” strategy, we present here mono‐ and disubstituted pyridyl–triazolyl–ferrocene units. The “pyridyl–triazolyl” chelating pocket is then used to chelate to copper(I) centers that additionally contain dppf [dppf = 1,1′‐(diphenylphosphino)ferrocene], which has an additional ferrocene moiety. This strategy delivers a heterotrinuclear (Fe–Cu–Fe) and a heteropentanuclear (Fe–Cu–Fe–Cu–Fe) complex. All complexes were characterized by 1 H and 13 C NMR spectroscopy and by mass spectrometry, and the heteropentanuclear complex was characterized by single‐crystal X‐ray diffraction. Electrochemistry and UV/Vis/NIR spectroelectrochemistry were used to investigate the redox properties of the complexes and to determine the site of electron transfer. The results presented here show the potential of “click”‐derived ligands in generating heteromultinuclear assemblies and the potential of ferrocene to function as a rigid, redox‐active unit in these assemblies.
