Ferrocene-driven single-chain polymer compaction

We introduce single-chain nanoparticles (SCNPs) exclusively folded by covalently bonded ferrocene units. Specifially, we demonstrate the ability of 2-ferrocenyl-1,10-phenanthroline to fuse single-chain collapse with the concomitant introduction of a donor functionality allowing the installation of a Pd-catalytic site, affording the first heterobimetallic ferrocene-functionalized SCNP. We introduce single-chain nanoparticles (SCNPs) whose folding is driven by ferrocene units while concomitantly carrying catalytically active species, establishing a bimetallic SCNP system that pushes the contemporary limits of SCNP design.
