C60 adsorbed on a monolayer of hexaazatriphenylene-hexanitrile (HATCN) on Ag(111) is investigated by ultraviolet photoelectron spectroscopy (UPS) and scanning tunneling microscopy. UPS and quantum-mechanical modeling show that HATCN chemisorbed on Ag(111) displays metallic character. This metallic molecular layer decouples C60 electronically from the Ag substrate and simultaneously acts both as template for the stable adsorption of isolated C60 molecules at room temperature and as "soft" metallic contact for subsequently deposited molecules.
通过紫外光电子能谱（UPS）和扫描隧道显微镜对吸附在Ag(111)上的六氮杂三亚苯六腈（HATCN）单层上的C60进行了研究。UPS和量子力学模型表明，化学吸附在Ag(111)上的HATCN具有金属特性。这种金属分子层使C60在电子上与Ag衬底解耦，同时在室温下既作为孤立C60分子稳定吸附的模板，又作为后续沉积分子的“软”金属接触层。
