Formation of Spherical Giant Molecules and Dynamic Behaviour of Supramolecular Assemblies Based on P_n-Ligand Complexes

Abstract

We report herein on our concept of using E_n-ligand complexes (E = P, As) as linking units for the creation of novel supramolecular ensembles. The reaction of these complexes with Group 11 metal salts of coordinating anions leads to the formation of insoluble oligomers, 1D and 2D polymers as well as soluble spherical nanoscaled clusters. In contrast, the reaction of E_n-ligand complexes with Group 11 metal salts of weakly coordinating anions yields soluble oligomers and polymers, which display monomer-oligomer equilibria in solution.
