Self‐Assembly of Au15 into Single‐Cluster‐Thick Sheets at the Interface of Two Miscible High‐Boiling Solvents

Wet (nano)blanket: The self-assembly of Au nanoclusters into single-cluster-thick nanosheets is performed in two miscible high-boiling solvents with a slight polarity difference, which generates microphase separation and acts as a soft template to direct the self-assembly in a two-dimensional orientation.
