On-surface synthesis of size- and shape-controlled two-dimensional Aun nanoclusters using a flexible fullerene molecular template

Abstract

Synthesizing nano-clusters with well-defined size, shape and composition without is an important and challenging goal in nanotechnology. Here we report the application of a single layer C60 molecules as an effective molecular template for the synthesis of size- and shape-selected two-dimensional gold clusters (Aun) on a graphite substrate. This molecular template facilitates preferential formation of Au19 clusters with selectivity as high as 90%. Density-functional-theory (DFT) calculations find an energy minimum associated with C60-stabilised two-dimensional Au19 clusters.
