采用配体交换反应制备了n -杂环碳包被金、钯纳米粒子；虽然碳烯从纳米颗粒表面定量地取代了硫醚和膦配体，但合成的纳米颗粒会自发地浸出金属配合物并在溶液中聚集。
N-Heterocyclic carbene coated Au and Pd nanoparticles have been prepared by a ligand exchange reaction; although carbenes quantitatively displaced the thioether and phosphine ligands from the nanoparticle surface, the resultant nanoparticles spontaneously leached metal complexes and aggregated in solution.
