Heterobimetallic Eu(iii)/Pt(ii) single-chain nanoparticles: a path to enlighten catalytic reactions

摘要

We introduce the formation and characterization of heterometallic single-chain nanoparticles entailing both catalytic and luminescent properties. A terpolymer containing two divergent ligand moieties, phosphines and phosphine oxides, is synthesized and intramolecularly folded into nanoparticles via a selective metal complexation of Pt( II ) and Eu( III ). The formation of heterometallic Eu( III )/Pt( II ) nanoparticles is evidenced by size exclusion chromatography, multinuclear NMR ( ~(1) H, ~(31) P{ ~(1) H}, ~(19) F, ~(195) Pt) as well as diffusion-ordered NMR and IR spectroscopy. Critically, we demonstrate the activity of the SCNPs as a homogeneous and luminescent catalytic system in the amination reaction of allyl alcohol.
