Supramolecular Polysulfide Polymers with Metal-Ligand Interactions

摘要

We report the first preparation of a supramolecular polysulfide polymer using metal-ligand interactions.The supramolecular polysulfide polymer was prepared by introducing 2,2'-bipyridine(bpy)at both ends of linear sulfur and linking the bpy with Cu~(2+).The molecular weight of the supramolecular polysulfide polymer was higher than polysulfide polymer obtained via conventional polymerization.Disassembly and reassembly of the supramolecular polysulfide polymers were controlled by de-metalation of Cu~(2+)from the complex between bpy and Cu~(2+)and re-formation of the complex with the addition of chelating agents and Cu~(2+),respectively.
