The Ni(II) complex of 5,10,15,20-tetrakis[3', 5'-di(2''-methylbutyloxy) phenyl] porphine was synthesized and characterized by (HNMR)-H-1, UV-vis spectroscopy and MALDI-TOF mass-spectrometry. The stationary phase on the base of synthesized Ni(II) complex was used for chromatographic separation of isomeric methyl-and dimethylpyridines. The high structural selectivity of this sorbent was explained by giving the results of DFT calculation of pyridine derivatives axial complexes with porphyrin Ni(II) complexes.
