Au(111) single crystals were cleaned by several sputtering and annealing cycles in ultrahigh vacuum. 7,16-Dibromo-5,14-dihydro-5a,14a-diaza-5,14-diboradibenzo[a,m]rubicene (B2N2-DBR) precursors were sublimated in ultrahigh vacuum (UHV) from a quartz crucible heated at 275 °C onto the sample kept at room temperature. Subsequent annealing of the substrate at appropriate temperatures initiates the formation of compounds 1 and 3 as discussed in the article.
