Abstract

Einbahnstraße: Eine neue Familie von λ5-Phospha[7]helicenen, die eindimensionale säulenartige Stapel im festen Zustand bilden, wurde synthetisiert (siehe Schema). Benachbarte Stapel haben entgegengesetzte Dipolrichtungen. Im Fall des Helicens auf Basis von racemischem Phospholsulfid bestehen Säulen mit einer der beiden Dipolrichtungen aus dem einen Enantiomer, Säulen mit entgegengesetzter Dipolrichtung aus dem anderen.
