Experiments on preparation of C60ONCFn cycloadduct (Fn=ferrocene) and C60(Cocp2)3 charge transfer complexes are described and their properties analyzed. The ferrocene derivative is bound to C60 at the 6-6 bond by a heterocyclic oxygen-nitrogen-carbon ring. The experimental results are compared with the results of modeling using semiempirical quantum chemistry PM3 model. Scanning tunneling microscopy and spectroscopy has been used to observe variation of electronic structure along capped carbon nanotubes deposited on freshly cleaved HOPG(0001) surface. The electronic structure has been derived from measured dependence of tunneling conductance dI/dV on the applied voltage. The evolution of dI/dV(V) along the nanotube are discussed in terms of existing theories of nanotubes and quantum chemistry calculations.
