Pyrroles represent a unique set of supramolecular „building blocks” that, depending on the nature and number of substituents, are capable of stabilizing a range of self-assembled entities in the solid state. In this paper, it has been prepared new molecular aggregates composed of a iron oxide and a functional polymer (polypyrrole) with oxo dimers of porphyrin spacers. The new system is characterized by FTIR, UV-Vis and SEM techniques. The particles of the new nanocomposite system was found to be spherical and average size was 80 nm.
