摘要
Coassembly of short molecular wires OPE1 with chiral analogues OPE2, both of which are CD silent, exhibited a sergeant-and-soldiers effect that resulted in transformation of vesicular aggregates of OPE1 into CD-active helical nanotubes (see schematic picture), as revealed by CD, dynamic light scattering, and atomic force and transmission electron microscopies (TEM). OPE = oligo(p-phenyleneethynylene). (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
