Abstract: Porphyrins and their analogues, due to their unique physicochemical properties,
have a wide range of applications. Synthetic tetraarylporphyrins with an asymmetric substituent
system are of particular interest. In this regard, an asymmetric porphyrin was synthesized,
containing a phenyl fragment on the periphery of the porphyrin macrocycle. Subsequent
quaternization of the compound with methyl iodide was carried out in order to obtain
water-soluble porphyrin. Its structure was confirmed by 1H NMR spectroscopy and
MALDI-TOF spectrometry. The photochemical properties and structural features of the
complexation of synthesized porphyrin with representative oligonucleotides poly[d(AT)2]
and poly[d(GC)2] have been studied. According to the results obtained, the studied compound
forms a highly stable complex with poly[d(GC)2] by the intercalation mechanism. In
the case of poly[d(AT)2], porphyrin binds in the minor groove.
