Notably, to illustrate the electronic structures and the molecular aromaticity of these GNRs, nucleus-independent chemical shifts (NICS) and anisotropy of the induced current densities (ACID) calculation on AR-11 and ARO-11 are conducted at the B3LYP/6-31G(d) level of theory based on the optimized structures (Figure and Figure , 18). The largely negative NICS(1)ZZ values (-22.9 to -27.6 of AR-11, -24.1 to -28.6 of ARO-11 in yellow) indicate that these six-membered rings exhibit local aromaticity. These analyses are further supported by ACID calculations, which show clockwise (diamagnetic) ring currents mainly distributed at hexagonal rings A/B/C/D/E/F at the outer rims of the whole π-framework. In addition, rings J/L in AR-11 and ARO-11 also display very negative NICS(1)ZZ values(-20.3 of AR-11, -20.6 of ARO-11), manifesting that they also contribute to the aromatic structures. However, the positive NICS(1)ZZ values of 13.3 suggest that these sulfur dioxide rings have no contribution to the overall πconjugation in Figure . The induced ring currents are relatively weak in the fused sulfur dioxide rings H/N of ARO-11, resulting in breaks for the global delocalization of the π-electrons (Figure ). These results demonstrate that the doping of sulfur dioxide achieves the delocalization of π-electrons in GNRs. e From CVs measured in THF (1.0 × 10 -5 M). The HOMO energy levels are adjusted according to the redox half potential of Fc/Fc + and estimated. according to the formula EHOMO (eV) = -(4.80 + Eonset ox1 -E(Fc/Fc + )) (also see Figure ).
