Since the discovery of carbon nanotubes (CNTs) in 1991 by Iijima, 1 synthetic tubular architectures are of great interest because of their exceptional properties and wide range of potential applications in material science, chemistry and biology. 2 In fact, significant progress has been made in the realms of organic or inorganic architectures. 3 Nevertheless, tubular metal–organic complexes are very rare. Up to now, only one tubular metal–organic architecture, based on a ...
