In the last years, chemists have devoted significant efforts to the synthesis of increasingly larger molecular structures that push boundaries of the molecular world into the nanoscale. Among these structures, molecular nanoribbons have received considerable both as synthetic challenges and as a unique platform to develop new materials because the nanoribbon structure dominates the optical, electronic, electrical, and magnetic properties. In these terms, we have introduced several approaches to prepare molecular graphene nanoribbons and nanographenes that reach dimensions (12.9 nm in length and 322 sp² atoms in the aromatic core) that exceed both the largest lengths reported for molecular nanoribbons and the largest aromatic cores reported for nanographenes [1-6]. The most recent advances in the synthesis of such giant molecular nanoribbons will be discussed.
