String quartets : Guanine molecules self‐assemble into a hydrogen‐bonded network of G quartets upon deposition under ultrahigh vacuum conditions onto Au(111) surfaces as shown by STM (see picture). The resilience of the H‐bonded network (stable up to 400 K) is explained through a cooperative increase in the strength of H‐bonds between guanine molecules in a quartet.
