Guanosine‐based Hydrogen‐bonded Scaffolds: Controlling the Assembly of Oligothiophenes

Abstract

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.
