Abstract

Abstract It is shown that the chiral ligand glutathione can induce active surface growth in the deposition of Au on Au nanoplates, forming nano‐badges with complex surface patterns. The special feature of the growth mode is that the growth materials are diverted to a few active sites, causing deep valleys and high standing walls. The circular dichroism signal depends on the tilting degree of the walls, which likely arises from the different packing of the chiral ligands on the two pro‐chiral slopes. As a characteristic sign of the Active Surface Growth mode, low seed concentration is used to promote the rate of deposition, which expands the ridge–valley competition favoring growth at the active sites. The understanding and rational control of the chiral ridges will advance the synthetic control for chiral nanostructures.
