Fig. 5. 13C NMR showing signals from the free C60 added as an external standard in the outer tube (reference) in deuterated tetrachloroethane and complexed C60 within the core of the crosslinked nanoparticle present in the inner tube (sample) also in deuterated tetrachloroethane. The internal tube diameter was 3 mm, while the external tube diameter was 5 mm.
