Decorating polymer beads with 1014 inorganic-organic [2]rotaxanes as shown by spin counting

Abstract

Polymer beads are used in the core of magnetic particles, and beads functionalised with paramagnetic molecules are promising as agents for dynamic nuclear polarization. Here, the authors use conventional click chemistry to decorate a polymer bead with 1014 [2]rotaxanes containing paramagnetic {Cr7Ni} rings.
