We report the synthesis of the C84(20)-fullerene related hydrocarbon C84H42, which possesses more than 83% of the C84(20)-fullerene connectivity, and its selective transformation to C84 by flash vacuum pyrolysis (FVP).

A short convenient synthesis of 6,7-benz[c]acephenanthrylene (2) is described. Solutions of C60 (1) in toluene exposed to laboratory lighting readily photodimerize to the cis-cyclobutane 14, with a molecule of toluene intercalated inside the molecular cleft.
We report the synthesis and purification of a C60H30 precursor molecule for the end-cap of a (6, 6) armchair and of a C54H24 precursor molecule for a (9, 0) zig-zag type single-wallednanotube. An approach to controlled growth of single-walledcarbonnanotubes is suggested.

−OH substituents, and its stronger influence relative to methyl groups, was also observed in the nitration and bromination reactions. Charge distribution modes in the regioisomeric protonated carbocations formed via parent B[c]Ph as well as in the benzylic carbocation formed via fjord-region epoxide ring opening were deduced by gauge-invariant atomic orbital density functional theory (GIAO-DFT) and
