摘要：

(Figure Presented) Mind your PQPs: 1D nanostructures were fabricated by the self-assembly of amphophilic centrally charged discotic 9-alkyl-2- phenylbenzo[8,9]quinolizino[4,5,6,7-fed]-phenanthridinylium (PQP) salts. Increasing the alkyl chain length of the PQP salts resulted in nanoscaled lamellar structures, whereas changing the counterion of the PQP salts from Cl- to BF4- led to a change from nanoribbons to helices and tubes. © 2007 Wiley-VCH Verlag GmbH S.
