Fig. 2

a STM image of TBTA/Ag(100) with coverage of 0.05 ML. b, c High-resolution STM images of an individual r-TBTA and s-TBTA on Ag(100). d, e Simulated STM images of r-TBTA and s-TBTA on Ag(100). The molecular structures of r-TBTA and s-TBTA are superimposed on the images for comparison. f, g Amplified STM images of the molecular rings and the chains in panel (a). Tunneling conditions: a Vbias = 1.0 V, It = 50 pA. b, c Vbias = −0.4 V, It = 100 pA. f, g Vbias = 1.0 V, It = 50 pA. Scale bars: a 20 nm. b–e 0.5 nm. f, g 2 nm.
