    "description": "On\u2010surface synthesis is a unique tool for growing low\u2010dimensional carbon nanomaterials with precise structural control down to the atomic level.\r\nOne of the most applied reactions to covalently interlink molecular precursors is dehalogenative aryl\u2010aryl coupling. \r\nFailures in this process are often related to the steric hindrance between reactants, which may arise due to their coplanarity upon adsorption on a surface. In a recent work we proposed a copolymerization approach to overcome the limitations that prevent intermolecular homocoupling. We used suitable linkers as additional reactants to demonstrate formation of fully conjugated polycyclic nanowires incorporating non\u2010benzenoid rings. This record contains data to support the experimental and theoretical evidences discussed in the manuscript.",
