(a) Large-scale STM image of the Co(TAP) molecules adsorbed on Au(111) at high coverage and after being annealed at 523 K. (b) Enlarged STM images of a disordered domain in (a). (c) Enlarged STM images of a well-ordered self-assembly domain in (a). The intermediate DHC products are marked by the white dashed circles in (b,c). The blue scale bars in (a–c) correspondingly represent 5, 2 and 1 nm. Imaging conditions: (a,b) −1.0 V, 30 pA; (c) −0.3 V, 10 pA.
