Supramolecular Aggregation of Flexible Polymers in High Melting Nanostructured Adducts

Flexible polymer chains and a suitable aromatic host self-assemble in varied ratios to fabricate crystalline and semi-crystalline materials with robust architectures. The high melting macromolecular adducts were successfully prepared by solvent-free mechanochemical or thermal treatment of the crystalline host and few polymers with various molecular weights. This unconventional strategy has been applied for the selective confinement of copolymer blocks into crystalline inclusion compounds, thus creating novel architectures stabilized by cooperative CH•••pi interactions, as revealed by solid state NMR.
