Abstract
Seven of the best: A dynamic combinatorial library of polycatenated tetrahedra was prepared by complexation between a dynamic Fe(4)L(6) tetrahedral cage, constructed from ligands containing an electron‐deficient naphthalenediimide core, and an electron‐rich aromatic crown ether, 1,5‐dinaphtho[38]crown‐10. The highest order species in the library is the tetrahedral [7]catenane.[Image: see text]
