Abstract

A key step in the on-surface synthesis of graphene nanoribbons is thermal annealing of polymer precursors on a metal substrate. Here, Maet al. decouple the cyclodehydrogenation reaction from the catalytic metal substrate and grow graphene nanoribbons by injecting charges at molecular sites.
