Side-chain meta[6]cycloparaphenylene-based nanoring-containing polymers

Abstract

We report the first controlled polymerization of the norbornene-functionalized meta[6]cycloparaphenylene (m[6]CPP) monomer through ring-opening metathesis polymerization (ROMP). The m[6]CPP nanohoop is incorporated as a pendant motif away from the polymer backbone. The intrinsic unique photophysical properties of m[6]CPP are largely retained when it is converted into a polymer. This work represents a convergence of precise organic synthesis and macromolecular chemistry toward functional carbon-based materials.
