Fig. 1 — a Chemical structure of prochiral 6,12-dibromochrysene 1 showing both the left- and right-handed enantiomers which are available on the surface. b Schematic of the organometallic polymers 2 formed upon deposition of monomer 1 on Ag(110) held at RT. c, d Overview STM images of the organometallic polymers 2 formed on Ag(110) upon deposition of 1 onto Ag(110) held at RT. e Close-up STM image of two organometallic polymers at an edge of a molecular island with an overlaid molecular model. Deposition was done onto a Ag substrate kept at RT. Scanning parameters: (c) −1.9 V, 10 pA, (d) −1.9 V, 5 pA, (e) 0.5 V, 100 pA. Color code: Br, red; Ag, blue; C, gray; H, white.
