摘要：
Small silver clusters Ag(n) (primarily probably Ag4 clusters which aggregate to Ag(n) (400 &lt; n &lt; 2000)) are generated in the immediate vicinity of a four-electron reducing agent (based on hydroquinone) which is incorporated in a monolayer of long-chain alkanethiols. The hydroquinone derivative is oxidized to quinone (see the picture). Molecularly resolved scanning tunneling microscopy (STM) images were obtained of self-assembled monolayers with and without silver clusters.
