Small silver clusters Ag n (primarily probably Ag 4 clusters which aggregate to Ag n (400< n <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.
