The synthesis, purification and characterization of seven isomeric nitrocyclopenta[cd]‐pyrenes (nitroCPPs) are described. Nitration of partially hydrogenated CPPs affords mixtures of nitro derivatives, which, after separation, are aromatized with DDQ. The resulting nitroCPPs are characterized by their 1H NMR, 13C NMR, UV‐vis, IR and mass spectra. The interaction between the nitro group and the aromatic system of CPP is discussed.
