“…To find a balance between the loose packing and pore blocking, one approach is to generate the complexity on the surface of MOPs. Indeed, there are few studies to induce such complexity by mixing multiple homoleptic cages or molecularly mixing multiple ligands to form heteroleptic cages; − however, the structure–porosity relationship of MOPs with such chemical complexity is still unclear.…”

Structure−porosity relationships for metal−organic polyhedra (MOPs) are hardly investigated because they tend to be amorphized after activation, which inhibits crystallographic characterization. Here, we show a mixed-ligand strategy to statistically distribute two distinct carbazole-type ligands within rhodium-based octahedral MOPs, leading to systematic tuning of the microporosity in the resulting amorphous solids.

Controlling supramolecular polymerization across various length scales through metal‐organic polyhedra in aqueous media enables functional nanomaterial fabrication beyond traditional π‐chromophoric systems. Herein, we present a straightforward strategy to tune the nano‐ and microscopic structural evolution of a co‐assembled system. Ga‐MOC ([Ga8(ImDC)12]12‐, ImDC = imidazoledicarboxylate) is introduced as a discrete unit, while the Ni‐ethylenediamine complex [Ni(en)3]2+ (Ni‐en), served as the binder towards supramolecular polymerization. Comprehensive investigations revealed that adjusting the binder ratio in the bicomponent (Ga‐MOC and Ni‐en) co‐assembly process allows precise control over nanostructure length and evolution by influencing both the kinetics and thermodynamics of the assembly. At higher concentrations, this assembly forms a hydrogel above a critical binder ratio. Furthermore, the binder's ratio significantly influences the viscoelastic strength of the hydrogels by modulating the connectivity between the MOCs through hydrogen (H)‐bonding. Intriguingly, the hydrogels gradually transformed into crystals without any external stimuli, with different timescales regulated by the binder ratio. Single crystal structure determination reveals a 3D structure composed of Ga‐MOC and Ni‐en, extended through charge‐assisted H‐bonding (CAHB) interactions, resulting through the transformation from a kinetically controlled gel state to a thermodynamically stable crystal product. This study provides an understanding of binder‐mediated control over nanostructural evolution in co‐assembled MOCs.
