Sequential self-assembly of calix[4]resorcinarene-based heterobimetallic Cd 8 Pt 8 nano-Saturn complexes.

A rational molecular design strategy is introduced for selective metal-ligand coordination, enabling the quantitative self-assembly of heterobimetallic nano-Saturn complexes. During the sequential multicomponent self-assembly, the Cd II ions and organometallic trans -Pt II motifs demonstrate preferential binding to specific ligands. The pre-designed directive interactions allow for precise control over the structural characteristics.
