The scaffolding of a π ‐conjugated oligomer, namely terthiophene, is achieved by taking advantage of the self‐assembly of a guanosine derivative into highly directional H‐bonded networks. Reversible interconversion allows switching between ribbons and quartet‐based assemblies in solution. The self‐assembly of 1 on surfaces lead to large lamellae of straight ribbons, ultimately forming 1D conjugated arrays as prototypes of supramolecular nanowires.
