Abstract

Variable Steuerung: 1D-Nanostrukturen wurden durch die Selbstorganisation amphiphiler zentral geladener diskotischer 9-Alkyl-2-phenylbenzo[8,9]chinolizino[4,5,6,7-fed]phenanthridinylium(PQP)-Salze erhalten. Längere Alkylketten in den PQP-Salzen führten zu nanoskaligen lamellaren Strukturen, der Wechsel des Gegenions der PQP-Salze von Cl zu BF4 dagegen verwandelte die Nanobänder in Nanohelices und -röhren.
