Lamellar structured carbon particles with layer thickness of 300～500 nm were synthesized through a novel route based on the self-assembly process of trichlovinyl benzene in benzene solvent at 300 ℃. In this process, benzene and hexachloroethane served as carbon sources to form trichlovinyl benzene based on Friedel-Crafts alkylation reaction in the presence of anhydrous aluminum chloride as catalyst. Under the same reaction conditions, carbon nanoflakes with thickness of 30～50 nm were induced by introduction of aluminum powders as substrate. It was also found the carbon products were composed of graphitic nanocrystallites and amorphous carbon. Moreover, the ledge growth mechanism of the lamellar structure and the heterogeneous nucleation mechanism of the carbon nanoflakes on aluminum surface were discussed.

Key words: benzene, Friedel-Crafts alkylation, building block, self-assembly, carbon nanoflakes
