The pyrrole core is a structural motif of particular interest in synthetic and medicinal chemistry, as it is present in a large number of natural products [1] and biologically active compounds.[2] Furthermore, cyclic [3] and linear π-conjugated oligo-and polypyrrolic systems are of growing relevance in materials science, supramolecular chemistry, and nanotechnology. For example, they have found application in anion binding,[4] cation ...
