On-Surface Synthesis of Nanographenes and Graphene Nanoribbons on Titanium Dioxide

The article describes the formation of two types of nanographenes from custom designed and synthesized molecular precursors, through thermally induced intramolecular cyclodehydrogenation reactions on the semiconducting TiO2(110)-(1×1) surface. The obtention of the nanographenes was confirmed by the...
