Abstract |
Carbon Nanohorns (CNHs) constitute a new allotrophic form of carbon and
are included in the wider family of carbon nanotubes (CNTs). Similarly with CNTs, CNHs represent a promising material for their use in nanotechnologycal and
biotechnological applications. In the present work, are presented the methodologies of chemical functionalization of CNHs as well as the first studies of these new hybrid
CNHs based material. More specifically, the chemical modification of CNHs was
achieved either by forming covalent bonds at the side walls or at the conical tips of CNHS, or by π-π interactions between aromatic planar organic molecules with the network of CNHs. In the all these cases, main purpose was the solubilization of CNHs in a abundance of organic solvents and in water systems, aiming the more
complete study and characterization of their spectroscopical features. Moreover, in the case of hybrid CNHs materials with photo-, elecro active groups, photophysical and electrochemical studies revealed the intrahybrid communication between the parts of the hybrid system, namely the CNHs and the photo- or elecro- active organic moiety, through charge transfer or energy transfer mechanisms. Such materials are promising for nanotechnological applications in the fields of energy conversion, fuel
cells and photovoltaic cells.
