Figure 27

(a) Schematic representation of the reactant, intermediate polymer, and nanoribbon end product during synthesis of 7-aGNRs. Associated STM images with the overlaid models are displayed below the polymer and GNR. Below, some representative reactants and associated microscopy images of the resulting GNRs (with superimposed wireframe structures) are displayed for varying GNRs. Different edge orientations are displayed (b, armchair; c, chiral; d, zigzag). Different widths of armchair ribbons are displayed (e, 5-aGNR; f, 9-aGNR; g, 13-aGNR). Different edge structures are shown (h, cove edge; i, chevron; j, fluoranthene functionalized zigzag edge). Differently doped structures are shown (k, boron heteroatoms; l, nitrile functional groups; m, N heteroatoms. (a, i) Adapted with permission from ref (151). Copyright 2010 Springer Nature.
