Porphyrins are large redox-active π-systems, which makes them interesting components for the construction of molecular wires. Template-directed synthesis can be used to prepare porphyrin nanorings with diameters in the range 2–20 nm, such as the 12-porphyrin nanoring illustrated below (Figure 1). This talk will summarize recent work on charge transport and charge delocalization through these molecules.
