Like beads on a string: A synthetic method for the directional construction of strings of spherical fullerenes along stacks of planar oligothiophenes is described. The key to success was the preparation of fullerenes with two solu-bilizing tri(ethylene gl

Two protocols based on Cu(i) template synthesis and click reactions for the synthesis of functionalized [2]catenanes are described. A straightforward procedure, involving high dilution conditions at high temperatures (70 °C), affords [2]catenanes bearing two identical peripheral groups in high yields. For the preparation of non-symmetrically functionalized [2]catenanes, a second milder and simpler protocol was developed, generalizing and extending the method. The introduction of peripheral functional groups into the catenane structure opens up possibilities of using [2]catenanes as building blocks for preparation of even more complex structures.

A Eullerene derivative bearing a benzaldehyde unit has been prepared and used as starting material for the synthesis of a formyl-fullerenoporphyrin building block. Condensation of this aldehyde with pyrrole in CHCl3 with BF3·Et2O as catalyst followed by p-chloranil oxidation yielded a pentaporphyrinic scaffold surrounded by four peripheral C60 subunits. By following a similar strategy, a bis-porphyrin building block bearing an aldehyde function was prepared and used for the construction of a nonaporphyrin array by reaction with pyrrole under typical porphyrin synthesis conditions. Whereas the 1H NMR spectrum recorded at room temperature for the nonaporphyrin system is well defined, the signals recorded under the same conditions for the pentaporphyrin derivative surrounded by four peripheral C60 groups are broad. Indeed, the C 60-pentaporphyrin ensemble appears as a mixture of conformers which equilibrate slowly on the NMR time scale at room temperature.

A strong effect on the redox properties of the porphyrin moiety is exerted by the four fullerene groups in 1 (R(= C12H25). The potential of the first oxidation step is significantly more anodic than that for an analogous porphyrin wi
