ABSTRACT
Birds of a feather flock together: STM and DFT studies provide the first example spontaneous chiral resolution helicene on surface. Racemic 6,13-dicyano[7]helicene forms fully segregated domains pure enantiomers (2D conglomerate) Cu(111). The propensity system to optimize intermolecular CN⋅⋅⋅HC(Ar) hydrogen bonding CN⋅⋅⋅CN dipolar interactions translates into recognition with preferential assembly homochiral molecules.
