Abstract

In a stable relationship: Watson-Crick hydrogen bonding plays a key role in stabilizing the highly ordered supramolecular porous structure formed by co-deposition of biomimetically modified nucleobases cytosine and guanine onto a Au(111) surface under ultrahigh vacuum conditions. A combination of high-resolution STM imaging and density functional theory has been used to determine the structure of the network (see picture).
