Abstract

Abstract : A novel "D3 –AC–E3 " triple-monomer methodology was proposed to construct supramolecular hyperbranched alternating polymers. Abstract : A novel "D3 –AC–E3 " triple-monomer methodology was proposed to construct supramolecular hyperbranched alternating polymers. Two rigid homotritopic monomers tris(per-methylated pillar[5]arene) (D3 ) and tris(benzo-21-crown-7) (E3 ), and a heteroditopic monomer bearing a dialkylammonium salt and a neutral guest moiety, were prepared. The supramolecular hyperbranched alternating polymer was formed by selective binding interaction between the pillar[5]arene moiety with the neutral guest moiety and between the benzo-21-crown-7 group and the dialkylammonium salt group. The triple-monomer system was found to effectively avoid the formation of cyclic oligomers/gels/precipitates usually formed in the traditional "A2 + B3 " double-monomer system. This study will be helpful in designing supramolecular hyperbranched polymers with controllable structure and function.
