Employing electrospray ion beam deposition, nonvolatile sucrose can be deposited on clean surfaces. In this Communication, we present the 2D crystalline assembly of sucrose on a Cu(100) surface. By combining scanning tunneling microscopy images and multi‐stage modelling, the conformation and assembly pattern of sucrose is revealed.
