Synthesis of New Carbon Compounds: N-doped Fullerene (C50N10)O3H10 and “Pyridine” Nanocarbon

Abstract

Fullerene N-doped fullerene (C 50 N 10 )O 3 H 10 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, (C 50 N 10 ). Nitrogen atoms in (C 50 N 10 )O 3 H 10 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 13 C and 1 H, massspectroscopy were used.

New Method of Generation of Carbon Molecules and Clusters

“…Earlier [25][26][27][28] we have been systematically studied the influence of various technological parameters on composition of obtained products and, in particular, condensed substances formed at heat treatment of hydrocarbons. On the basis of the experimental results the new method of pyrolysis (NMP) of organic vapours was developed [28][29][30][31]. This method differs from two already known processes of pyrolysis [32].…”

“…Pyridine (C 5 NH 5 ) is heterocyclic analogue of benzene (С 6 Н 6 ) therefore from precursors C 5 N or С 3 -С 5 should be formed accordingly heteroatomic or monoatomic fullerenes and quasi-fullerenes. Our preliminary researches [29,30] have shown that at pyridine pyrolysis large nitrogen-carbon containing molecules are formed which further study represents not only scientific but also practical interest.…”

Szeged Matrix Property Indices as Descriptors to Characterize Fullerenes

“…Fullerenes received attention from the researchers all over the word and led to the synthesis of new compounds [1][2][3][4] and identification of different applications due to their hardness, high electron affinity, increased incident light intensity, and biological activities [5][6][7].…”
