To circumvent the problems, we decided to design zigzag-type aromatic belts by embedding five-membered pyrrole rings into the belt structures. We envisioned that to stitch all fjords of pre-halogenated nitrogen-linked calix [n]arenes F by means of multiple intramolecular carbon-carbon homocoupling reactions would lead straightforwardly to the formation of Ndoped aromatic belt compounds G (Fig. ). Being different from belt [n]arenes consisting of only hexagonal aromatic sub-units, incorporation of pentagonal pyrrole rings would generate unprecedented aromatic belts of truncated cone or spherical frustum. It is of great importance to reveal their structures and electronic features and to exploit their applications in chemistry and materials.
