Two-dimensional self-assembly of disulfide functionalized bis-acylurea: a nanosheet template for gold nanoparticle arrays.

A new functional bis-acylurea molecule allows a two-stage self-organization process. It self-organizes--at first--into 2D nanosheets with disulfide groups at the surface, which act--in the second stage--as a template for gold nanoparticle arrays.
