Dendrimers Based on Electroactive Metal Complexes. A Review of Recent Advances

Abstract

Recent studies in the field of dendrimers based on electroactive metal complexes are reviewed. The electroactive units may be present (i) in the core, (ii) in the branches, (iii) in the surface, (iv) in the core and in the branches, (v) in the core and in the surface, (vi) in the branches and in the surface, and (vii) in the core, branches and surface. Depending on the dendrimer structure, the electroactive units can either interact or behave independently. The most interesting features are the shielding of electroactive cores by non electroactive branches, the great number of electrons that can be exchanged in a very narrow potential region by high generation surface-functionalized dendrimers, and the tailor-made redox patterns that can be obtained by dendrimers based on metal complexes at each branching centre.
