Grafting of gold onto spin-crossover nanoparticles: SCO@Au

Nanoparticles of gold were successfully grafted onto nanoparticles of a 1D polymeric spin-crossover material leading to singular SCO@Au hybrid particles. The result is equally obtained using a large range of gold-particle sizes, from 4 to 45 nm, which first allows definition of the best experimental conditions, notably in terms of gold-particle concentration, and then demonstrates the robustness and the efficiency of the method.
