Abstract
- Polymer beads have been used as the core of magnetic particles for around twenty years. Here we report studies to attach polymetallic complexes to polymer beads for the first time, producing beads of around 115 microns diameter that are attached to 1014 hybrid inorganic-organic [2]rotaxanes. The bead is then formally a [1014] rotaxane. The number of complexes attached is counted by EPR spectroscopy after including TEMPO radicals within the thread of the hybrid [2]rotaxanes. 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. [ABSTRACT FROM AUTHOR]
