1,3-Phenylene-bridged naphthalene wheels synthesized by one-pot Suzuki–Miyaura coupling and the complex of the hexamer with C60†
A large 1,3-phenylene-bridged hexameric naphthalene wheel N6 and a heptameric wheel N7 were synthesized simply by Suzuki–Miyaura coupling via one-pot reaction from monomers. We could control the distribution of N6 and N7 via the reaction conditions. The hexameric wheel structure was revealed by X-ray diffraction analysis. The wheel N6 exhibited C60 encapsulation ability in the solid state, which was also confirmed by single crystal X-ray analysis.
