Heterochiral recognition among functionalized heptahelicenes on noble metal surfaces

Chiral recognition among three differently functionalized heptahelicene derivatives on Ag(111) and Au(111) surfaces has been studied with scanning tunnelling microscopy. All three species were found to self-assemble into racemic zigzag structures, with alternation of ( M )- and ( P )-enantiomers. No...

Summary:Chiral recognition among three differently functionalized heptahelicene derivatives on Ag(111) and Au(111) surfaces has been studied with scanning tunnelling microscopy. All three species were found to self-assemble into racemic zigzag structures, with alternation of ( M )- and ( P )-enantiomers. No matter which heptahelicene derivative, all assemble into heterochiral zigzag chains on gold and silver(111) surfaces.
