TL;DR: Cai et al. as discussed by the authors used a surface-assisted coupling of the precursors into linear polyphenylenes and their subsequent cyclodehydrogenation to produce GNRs of different topologies and widths.

TL;DR: This work reports a simple method for the production of atomically precise graphene nanoribbons of different topologies and widths, which uses surface-assisted coupling of molecular precursors into linear polyphenylenes and their subsequent cyclodehydrogenation.

TL;DR: By surface-assisted coupling of specifically designed molecular building blocks, the fabrication of regular two-dimensional polyphenylene networks with single-atom wide pores and sub-nanometer periodicity is demonstrated.

TL;DR: It is shown that different balances between diffusion and intermolecular coupling determine the observed branched and compact polyphenylene networks on the Cu and Ag surface, respectively, demonstrating that the choice of the substrate plays a crucial role in the formation of two-dimensional polymers.

TL;DR: The possibility to use bottom-up approaches to fabricate a filter with porous graphene and analyze its functionality with first principle calculations is investigated and the porous network exhibits an extremely high selectivity in favor of H(2) and He among other atmospheric gases.
