Photoinduced deposition of size-controlled gold nanoclusters onto the self-assembled monolayer of 1,9-nonanedithiol

摘要

Gold nanoclusters are formed photochemically in organic solvent to give nanometer-scale islands on the self-assembled monolayer (SAM) of 1,9-nonanedithiol. The size and shape are variable by choosing electron-donating organic solvents, in ethanol, the plate-like nanoclusters are produced with layer-by-layer growth to give atomically nat top. The nano-structures are formed in N, N-dimethylformamide to give larger size than those in ethanol under comparable conditions. [References: 9]
