Helical Nanostructure of Achiral Silver p-Tolylacetylide Molecules

Abstract EN

Silver p-tolylacetylide is an achiral molecule; however, its nanostructure has been found to consist of twisted nanoribbons.

The twisted ribbon is a helicoid that combines translation and perpendicular rotation along the ribbon axis.

A helix, a typical chiral structure, can be created by the aggregation of achiral molecules, and the recrystallization conditions control the twist of the nanoribbons.

Therefore, the recrystallization controls the chirality.
