Synthesis of New Carbon Compounds: N-doped Fullerene (C50N10)O3H10 and “Pyridine” Nanocarbon
Fullerene N-doped fullerene (C50N10)O3H10 has been synthesized at thermal transformation of pyridine molecules. The synthesis was carried out at special reaction conditions, which are optimum for polycondensation of pyridine molecules. O and H atoms bind to nitrogen atoms and they are positioned exohedrally with respect to the pyridine net, (C50N10). Nitrogen atoms in (C50N10)O3H10 molecule reside in a hypercoordinated state: there are four bonds with carbon atoms belonging to the pyridine net and one bond is realized either with surface oxygen atoms (participating in 3 N–O–H bonds) or hydrogen (participating in 7 N–H bonds). N-doped nanocarbon (or “pyridine” nanocarbon) has also been synthesized with content of nitrogen not less than 10%wt. containing pyridine (not graphene) fragments. Methods of FTIR, XPS, X-ray diffraction patterns, NMR 13C and 1H, mass-spectroscopy were used.
