The discovery of N-heterocyclic carbenes (NHCs) revolutionized organometallic chemistry due to their strong metal-ligand bonds. These strong bonds also lend enhanced stability to gold surfaces and nanoparticles. This stability and high degree of synthetic tunability has allowed NHCs to supplant thiols as the ligand of choice when functionalizing gold surfaces. This review article summarizes the basic science and applications of NHCs on gold surfaces and gold nanoparticles. Additionally, scientific questions that are unique to gold-NHC systems are discussed, such as the NHC adatom binding motif and the NHC surface mobility. Finally, new applications for NHCs on gold are covered with particular attention to biomedicine, catalysis, and microelectronics.
N-杂环卡宾（NHCs）的发现彻底改变了有机金属化学，因为它们具有很强的金属-配体键。这些强键还增强了金表面和纳米颗粒的稳定性。这种稳定性和高度的合成可调性使得NHCs在功能化金表面时能够取代硫醇成为首选配体。这篇综述文章总结了NHCs在金表面和金纳米颗粒上的基础科学和应用。此外，还讨论了金-NHC体系特有的科学问题，如NHC吸附原子结合基序和NHC表面迁移率。最后，介绍了NHCs在金上的新应用，特别关注生物医学、催化和微电子领域。
