Abstract The supramolecular self-assembly of brominated molecules was investigated and compared on Cu (110) and Cu (110)[BOND] O (2× 1) surfaces under ultrahigh vacuum. By using scanning tunnelling microscopy, we show that brominated molecules form a disordered structure on Cu (110), whereas a well-ordered supramolecular network is observed on the Cu (110)[BOND] O (2× 1) surface. The different adsorption behaviors of ...
