“…In 2018, Sinitskii and co‐workers further synthesized a laterally extended chevron‐type GNR that contained an additional benzene ring in the elbow positions using a new monomer 14 (Figure 4c,d). [ 89,91 ] The lateral extension of the chevron‐type GNR resulted in a small reduction in the bandgap from 1.61 to 1.38 eV according to density functional theory (DFT) calculations. [ 92 ]…”

“…However, difficulties occur in the precise control of the length among different segments. In order to better control the proportion of the corresponding ribbon's units of GNRs, Costa et al explored the preparation of heterojunctions with the chevron backbone ( Figure a) by adjusting the ratios of the two precursors . Their investigation indicated that an equimolar amount of precursors resulted in the formation of the different nanoribbon's units of approximately in a 1:1 ratio (Figure b).…”

“…For GNRs with armchair edges, ribbons can be classified into three families according to their width; they are N=3p, N=3p+1 and N=3p+2 (p is an integer number and N is the number of carbon atom pairs across the ribbon) . When N=3p and N=3p+1, AGNRs have larger band gaps, that scale inversely with the ribbon width.…”

“…used molecule 1 and molecule 6 to prepare 7/13‐ AGNR heterojunction (Figure j) and its electronic structure at the interface position was identified by STM dI/dV spectroscopy (Figure k) . In addition, molecule 23a and molecule 33 can also sucessfully fabricate chevron/extended chevron heterojunctions (Figure l) . However, use of multi‐monomers may increase the random probability, that yields impurity GNR heterojunctions.…”
