ConspectusIn recent years, multicomponent self-assembly has emerged as a pivotal strategy in supramolecular chemistry, enabling the construction of artificial systems with enhanced functionalities that surpass those individual molecular components. These assemblies have garnered significant interest due to their potential applications recognition, catalysis, and biomedical engineering. However, achieving precise control over assembly process remains challenge, increased structural complexity often results thermodynamic mixtures, limiting practical applications. In this context, metal-coordination-driven promising strategy, moderate strength good directionality metal-ligand bonds ensure formation discrete architectures well-defined structures geometries. Notably, integration pyridyl carboxylate donors cis-Pt(II) nodes offers an effective approach for constructing metallacages. This method is particularly attractive its ability enable heteroleptic assembly, along accessibility tunability ligands, which impart desirable photophysical properties anticancer activities.This Account provides comprehensive overview our work on design, preparation, functionalization metallacages via ligands nodes. By strategically tailoring ligand adjusting number coordination sites, we successfully constructed diverse geometries, including tetragonal hexagonal prisms, triple-cavity ladders, truncated octahedra, cyclic bis[2]catenanes, etc. particular, highlight use functional such tetraphenylethylene, hexaphenylbenzene, perylene diimide, porphyrin derivatives, explore these Tetraphenylethylene hexaphenylbenzene derivatives are propeller-shaped molecules aggregation-induced emission properties, enhancing both solution solid state. Perylene diimide electron-deficient, planar conjugated structures, contribute strong solution, thereby improving host-guest chemistry luminescent Porphyrin owing excellent photosensitivity, endow photocatalytic capabilities. Additionally, other phenanthroline triazine been employed antibacterial SO2 adsorption respectively, Furthermore, metallacage-cross-linked networks exhibit mechanical superior processability, making them candidates materials.

Abstract The construction of supramolecular networks with novel crosslinks is great significance in expanding their chemical structures and exploring advanced functions. Herein, we prepare a type [2]catenane‐cored based on the crosslinking polyethylene glycol (PEG) using heterometallic [2]catenane unit. By adjusting molecular weight PEG, solubility can be tuned gels are formed low PEG. introduction offers good antibacterial properties owing to synergistic antimicrobial activity Pt(II) Cu(I) ions [2]catenane. This study provides simple efficient strategy for constructing topological as materials, which will promote structural design biological applications networks.
