Abstract

original image

Verdrehte Bänder wurden durch Selbstorganisation racemischer Alaninderivate gebildet (mittleres Bild), während einzelne Enantiomere nur zu flachen Nanostrukturen führten (links). Die Verdrehung spricht auf geringe Enantiomerenüberschüsse an und zeigt eine bemerkenswerte makroskopische Chiralität. Der Effekt kann genutzt werden, um Aminosäurederivate zu differenzieren (rechts) und ermöglichte sogar die Bestimmung der ee-Werte eines gemischten Systems.
