Synthesis of fullerene-porphyrin complex

摘要

C-60-porphyrin complex (1) has been synthesized for the first time. In this complex, two functional molecules are linked by a direct metal-C-60 bond. Characterization of 1 is performed with a H-1 and C-13 NMR and an electrospray ionization mass-spectroscopy(ESI-MS). The UV/Vis spectrum of 1 in benzene showed the strong absorption positioned at 280 and 326 nm assigned to the electronic transitions in C-60 moiety, which were red-shifted by 3 nm and blue-shifted by 7 nm with respect to those of pristine C-60, respectively. A new absorption band at lambda(max)=780 nm appeared in a longer-wavelength region. This band was assigned to metal-to-ligand charge transfer (MLCT) transition from ruthenium to fullerene.
