Fig. 6. CHNP, 5. (a, e) CHNP structure with its two observed enantiomers 5a and 5b. The strength of the colored circles indicate the magnitude of the deflection of the C atoms out of planarity. (b–d) CO tip AFM images of 5a on Cu(111) at different tip heights. (f, g) CO tip STM image of 5a before (f) and 5b after (g) enantiomerization with a voltage pulse of V = –0.4 V. The dashed line indicates the mirror plane of the transformation. (h) Fully aromatized molecule after removing four H atoms from the aliphatic ring with voltage pulses between 3.1 V and 3.8 V.
