Controlled self-assembly manipulated by charge-transfer interactions: From tubes to vesicles

Abstract

Transfer request: A self-assembled-supramolecular charge-transfer complex of 1-(11-oxo-11-pyren-1-ylmethoxy)undecyl)-pyridinium bromide (PYR) and ethane-1,2-diyl bis(3,5-dinitrobenzoate) (DNB) is shown to form vesicular aggregates in aqueous solution, in contrast to the tubular aggregates of pure PYR (see picture). A curvature-dependent mechanism for this change is proposed. (Figure Presented) © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
