Effect of a three-dimensional hyperbranched structure on the ionic conduction of metallo-supramolecular polymers
Abstract
Fe(II)-, Co(II)- and Ni(II)-based metallo-supramolecular polymers with three-dimensional (3D) hyperbranched structures (3D-polyFe, 3D-polyCo and 3D-polyNi) showed highly humidity-responsive ionic conductivity. The 3D polymers exhibited 10–100 times higher ionic conductivity than their 1D linear equivalents due to the improved ion conduction pathway in the amorphous 3D structure.
