Proof of Principle: Immobilisation of Robust CuII3TbIII-Macrocycles on Small, Suitably Pre-functionalised Gold Nanoparticles

Abstract

In a proof-of-principle study, a soluble macrocyclic single-molecule magnet (SMM) containing a CuII3TbIIImagnetic core was covalently grafted onto small gold nanoparticles pre-functionalised with carboxylate-terminated tethers. A modified microemulsion method allowed production of the small and monodisperse nanoparticles (approximately 3.5 nm in diameter) for the chemisorption of a large amount of intact macrocyclic complexes in the hybrid system.
