“…Coordination-driven self-assembly has been proven to be an effective approach for constructing supramolecular structures, due to its high predictability 1 – 6 . As such, a variety of discrete metallo-supramolecular architectures have been fabricated through different types of self-assembly strategies, including the coordinations of pyridyl 7 , bipyridyl 8 , terpyridyl 9 , or heterotopic ligands 10 – 12 with naked metal ions or metal-organic components 13 , 14 . Given the increasing demands for diverse and predesigned molecular structures and functions, scientists are encouraged to further develop novel building blocks to achieve high coordination selectivity in precise and controllable supermolecular assembly.…”

Coordination-driven self-assembly is a powerful approach for the construction of metallosupramolecules, but designing coordination moieties that can drive the self-assembly with high selectivity and specificity remains a challenge. Here we report two ortho-modified terpyridine ligands that form head-to-tail coordination complexes with Zn(II). Both complexes show narcissistic self-sorting behaviour. In addition, starting from these ligands, we obtain two sterically congested multitopic ligands and use them to construct more complex metallo-supramolecules hexagons. Because of the non-coaxial structural restrictions in the rotation of terpyridine moieties, these hexagonal macrocycles can hierarchically self-assemble into giant cyclic nanostructures via edge-to-edge stacking, rather than face-to-face stacking. Our design of dissymmetrical coordination moieties from congested coordination pairs show remarkable self-assembly selectivity and specificity.

Coordination-driven self-assembly serves as a powerful approach for the construction of metallo-supramolecules, however, it still remains its infancy in design of coordination moieties with high selectivity and specificity. Herein, two unique ortho-modified terpyridine ligands (MA and MB) were designed and synthesized to form head-to-tail coordination complexes with Zn(II) respectively. Both of them showed excellent narcissistic self-sorting process due to the exquisite design. Further, two multitopic ligands (LA and LB) with narcissistic self-sorting moieties were obtained and used to construct more complex metallo-supramolecules hexagons. More interestingly, because of the non-coaxial structural restrictions in the rotation of terpyridine moieties, the obtained hexagonal macrocycles were able to hierarchically self-assemble into giant cyclic nanostructures via side-to-side stacking rather than face-to-face stacking. Our design of dissymmetrical coordination moieties could pave a new avenue for the development of congested coordination pairs with high selectivity and specificity.

“…Metal-mediated self-assembly continues to spark the vibrant field of supramolecular chemistry, owing to its ability to deliver molecular architectures of aesthetic appeal . Over the past few years, more intricate coordination-driven self-assembled structures, such as sphere-in-sphere polyhedrons, multilayer polygons, , and multicavity cages, have been documented. Concurrently, such molecules possess diverse potential functions in host–guest chemistry, catalysis, drug delivery, stabilizing media, etc.…”

A series of stellated metallosupramolecular architectures have been assembled through threecomponent integrative self-sorting. Building on the complementary ligand pairing, the initial attempts to synthesize the hexagram complex from a combination of X-shaped tetrakis-and V-shaped bis-terpyridine ligands, and Cd II ions, resulted in an unprecedented mixture of stellated octanuclear and dodecanuclear metallocages, which were further isolated by column chromatography. To overcome the unexpected obstacle, the multivalent ligand design along with spontaneous heteroleptic complexation was applied to realization of the one-pot synthesis of the intricate topology. A centrally situated triangle served as a prop for quantitative formation of the six-pointed stellated complex. Notably, in the absence of the triangular prop, a four-pointed star was produced.
