From an Eight-Component Self-Sorting Algorithm to a Trisheterometallic Scalene Triangle

Using motifs from 3-fold completive self-sorting in an eight-component library, we report on the design and fabrication of a fully dynamic trisheterometallic scalene triangle, a demanding supramolecular structure that complements the so far known triangular structures.

From 3-fold completive self-sorting of a nine-component library to a seven-component scalene quadrilateral.

Three-fold completive self-sorting of a nine-component library with ≥126 possible combinations led to the clean formation of only three heteroleptic metal-ligand complexes. Due to the orthogonality of the latter, they were used as corner stones in an integrative self-sorting approach toward a seven-component scalene quadrilateral.

Preparation of a Poly-nanocage Dynamer: Correlating the Growth of Polymer Strands Using Constitutional Dynamic Chemistry and Heteroleptic Aggregation

A metallosupramolecular prismatic nanocage with altogether six reactive aldehyde terminals was utilized as a sophisticated monomer in a template-directed constitutional dynamic imine polymerization to prepare an unprecedented triple-stranded dynamer. To analyze the correlated growth in its three congener strands, a fully covalent triple-armed star polymer was fabricated from the metallodynamer through capping, imine reduction, and removal of the template. Atomic force microscopy analysis of 68 triple-armed star polymer molecules suggests that the growth of their arms is correlated to ~72%.

Scaffolding a cage-like 3D framework by coordination and constitutional dynamic chemistry.

By exploiting the supramolecular assistance of a sterically encumbered phenanthroline-Cu(+) motif, we report on the self-assembly of a trigonal nanoprism, its post-self-assembly functionalization, and transformation into a cage-like 3D framework with distinct compartments.
