The recognition of heterocyclic amines and their possible capture from polluted waters by porphyrins represents an ecological challenge. A novel metalloporphyrin bearing a pyridine functional group, Zn (II)-4-pyridyl-tris-(4-phenoxyphenyl) porphyrin (Zn-PyPPP), with high steric hindrance, whose base ligand was synthesized and characterized in our group, was used for a comparative study in order to investigate how the substituent –CH3 group of 1-methyilimidazole would influence the access of the free nitrogen atom to the Zinc atom of the porphyrin, in comparison to pyridine, despite the fact that the whole molecule is smaller than the six-membered cyclic compound. As expected, the performance is lower by using 1-methylimidazole.The formed complexes were also morphologically studied by means of AFM measurements.Keywords: metalloporphyrin, heterocyclic amines, UV-vis spectrometry, AFM imaging
