Multi-walled carbon nanotubes with the pyridine-containing fragment and copper(II) ions

Modified multi-walled carbon nanotubes (MWNT)-CO-L (L = NHCH 2 C 5 H 4 N) were synthesized. The possibility of their interaction with magnetically active binuclear complex Cu 2 (Piv) 4 (HPiv) 2 was shown. The presence of copper( ii ) ions on the surface of the reaction product, {Cu}@MWNT-CO-L, was suggested and confirmed by the data of thermogravimetry combined with mass spectral analysis, ESR spectroscopy, atomic absorption spectrophotometry, and electron microscopy (TEM and SEM).
