Hierarchical Self-Assembly: Well-Defined Supramolecular Nanostructures and Metallohydrogels via Amphiphilic Discrete Organoplatinum(II) Metallacycles
Metallacyclic cores
provide a scaffold upon which pendant functionalities
can be organized to direct the formation of dimensionally controllable
nanostructures. Because of the modularity of coordination-driven self-assembly,
the properties of a given supramolecular core can be readily tuned,
which has a significant effect on the resulting nanostructured material.
Herein we report the efficient preparation of two amphiphilic rhomboids
that can subsequently order into 0D micelles, 1D nanofibers, or 2D
nanoribbons. This structural diversity is enforced by three parameters:
the nature of the hydrophilic moieties decorating the parent rhomboids,
the concentration of precursors during self-assembly, and the reaction
duration. These nanoscopic constructs further interact to generate
metallohydrogels at high concentrations, driven by intermolecular
hydrophobic and π–π interactions, demonstrating
the utility of coordination-driven self-assembly as a first-order
structural element for the hierarchical design of functional soft
materials
