  The covalent functionalization of carbon allotropes represents a main topic
in the growing field of nano materials. However, the development of functional
architectures is impeded by the intrinsic polydispersibility of the respective
starting material, the unequivocal characterization of the introduced
functional moieties and the exact determination of the degree of
functionalization. Based on a novel carbon allotrope functionalization
reaction, utilizing {\lambda}^3-iodanes as radical precursor systems, we were
able to demonstrate the feasibility to separate and to quantify thermally
detached functional groups, formerly covalently linked to carbon nanotubes and
graphene via TG-GC/MS.
