Synthesis, electrochemical properties and self-assembly of a proton-conducting core-shell macromolecule

Let the protons flow: The synthesis of a core-shell macromolecule bearing phosphonic acids is presented. The rigid central core serves as a scaffold to stabilize the flexible polymer shells. Pronounced proton conductivity is obtained under humidified conditions. The self-assembly of such dendritic macromolecules by electrostatic interactions on a modified gold substrate is investigated and characterized.
