a–d STM images reveal the nucleation and the growth of the 2D homochiral HCBs of TBTA on Ag(111). Molecular coverage: a 0.2 ML, b 0.4 ML, c 0.8 ML, d 1.0 ML. Tunneling conditions: a, Vbias = 0.6 V, It = 50 pA. b, Vbias = 0.5 V, It = 50 pA. c, Vbias = 2.3 V, It = 60 pA. d, Vbias = 1.0 V, It = 50 pA. Scale bars: a–c 20 nm. d 10 nm.
