Summarizing the results for the I-BOPHY-I molecules deposited on Au(111), two phases coexist at RT, the most extended one assigned to self-assembled I-BOPHY-I molecules and a minority phase of metal-organic dimers, I-BOPHY-Au-BOPHY-I, formed upon initial molecular dehalogenation. When the system is annealed at 370 K, the I-BOPHY-I molecules dehalogenate, inducing the formation of 1D metal-organic oligomers, (Au-BOPHY)n mediated by the native adatoms of the surface. Interestingly, the growth process is completely stochastic, with the molecular chirality playing no role in it.
