employed by these workers is by grafting aryl groups through
diazotization reaction [45]. Soluble graphene layers in THF can be
generated by the covalent attachment of alkyl chains to graphene layers
via reduction of graphite fluoride with alkyl lithium reagents [46]. Such
covalent functionalization enables solubilization in organic solvents such
as CCl

and THF (Fig. 6(a)) [35]. Similar procedures have been
employed by Subrahmanyam
