These carbon materials were predicted to be moderately aromatic with moderately large positive %E(tr)s. They are presumably less aromatic than graphite and carbon nanotubes, but must be appreciably more aromatic than fullerenes such as C-60 and C-70. It seems that superaromaticity arising from torus-shaped super-ring structures is negligible. 关键词: HETEROPOLY TUNGSTOPHOSPHATE; REDOX; ELECTROCATALYSIS; CYCLIC VOLTAMMETRY; RESONANCE ENERGIES; GRAPHITIC CARBON; TOROIDAL FORMS; FULLERENES; HYDROCARBONS HYDROCARBONS
