用光学方法研究了有机吸附剂与金属表面的电子耦合效应。在Au（111）衬底上覆盖一层超薄（类似于0.3 nm）的扁平分子纳米石墨烯层，在很大程度上导致了进一步分子层的解耦。我们的工作表明，不仅无机盐或氧化物可以用作绝缘间隔，而且还可以用作特定的有机单层。
Electronic coupling effects of organic adsorbates to metallic surfaces are examined optically. Covering a Au(111) substrate with an ultrathin (similar to 0.3 nm) nanographene-like layer of flat lying molecules leads to decoupling of further molecular layers to a large extent. Our work suggests that not only inorganic salts or oxides can be used as insulating spacers but also particular organic monolayers.
