Abstract : The on-surface dehydrogenation of bispentahelicene on a gold(111) surface has been studied by means of scanning tunneling microscopy. Deposition of 2,2'-Bispentahelicene onto a gold surface in ultrahigh vacuum leads exclusively to formation of the homochiral (M,M)-and (P,P)-diastereomers. Thermally induced

Keywords : chirality scanning tunneling microscopy on-surface chemistry helicenes polyaromatic hydrocarbons Manuscript Classifications: Chirality Monolayers Scanning probe microscopy Surface chemistry
