  Synthetic Approaches to a Variety of Covalently Linked Porphyrin−Fullerene Hybrids

  摘要：

  There is substantial interest in dyads in which C-60 is covalently linked to electron donors, such as porphyrins, which absorb light strongly in the visible region. We present here the details of the syntheses of such compounds, which can be broadly organized into categories depending upon the nature of the linker joining the two chromophores. The structural aspects of intramolecular electronic interaction that we have sought to explore have dictated the synthetic strategies employed to generate these classes of molecules. Flexible glycol linkers were used to allow close approach between the fullerene and porphyrin, facilitating through-space interactions. These linkers also allowed studies of the effects of metal cation complexation. Naphthalene and alkyne linkers were used to examine the possible effects a conjugated or aromatic linker might have on photophysical properties. Finally, steroids were used as linkers in dyads expected to possess a large distance between the two chromophores, in which only through-bond interactions between the fullerene and porphyrin should be possible.

  Synthesis and photophysics of a novel porphyrin-C60 hybrid

  摘要：

  In the pursuit of a porphyrin-fullerene linked hybrid with increased solubility and superior cation complexation abilities, hybrid 1 was synthesized. The amphiphilic hybrid 1 was found to be slightly soluble in DMSO, displayed a lower affinity far metal cations than expected, and had a surprisingly high quantum yield (Phi(Delta)) for formation of singlet oxygen (O-1(2)).
