Fig. 3: Cyclodehydrogenation towards synthesis of 4.
From: On-surface synthesis of nitrogen-doped nanographene with an [18]annulene pore on Ag(111)
a Large-scale STM topography of the nitrogen-doped NGs on Ag(111). The inset shows a close-view image of single molecule. b Constant height dI/dV mapping of the product and (c) the corresponding chemical structure. Measurement parameters: V = 200 mV and I = 4 pA in a. For constant height dI/dV map:V = 10 V, Vac = 10 mV in b.
