The synthesis of N-doped zigzag-type aromatic belts is depicted in Fig. . The nitrogen-linked calix [n]pyridines 3a-c (n = 6 -8) were prepared from the palladium-catalyzed dual C-N bond coupling reactions between reactants 1 and 2. Selective bromination reaction of 3a-c proceeded smoothly and efficiently with bromine at ambient temperature in DCM to produce polybrominated Nn-calix [n]pyridines 4a-c in good yields. X-ray molecular structures illustrated in Figs. and show that the macrocyclic skeletons of 4a and 4c
