Nanorods versus Nanovesicles from Amphiphilic Dendrofullerenes
摘要:
Three new amphiphilic dendrofullerenes endowed with 4, 8, and 16 carboxylic groups have been efficiently prepared by using a click chemistry methodology. These amphiphilic fullerene derivatives aggregate forming micelles, nanorods, or hollow vesicles depending on the concentration and on the solid substrate.
C(60) derivatives bearing either terminal alkyne or azide functional groups have been prepared and used as building blocks under the copper-mediated Huisgen 1,3-dipolar cycloaddition conditions leading to 1,2,3-triazole derivatives. (C) 2008 Elsevier Ltd. All rights reserved.

A series of amphiphilic glycodendro[60]fullerenemonoadducts were efficiently synthesized using the CuAAC "click chemistry" approach. These glycodendrofullerenes can self-assemble in aqueous media, in a process favoured through π-π interactions between the [60]fullerene moieties. This aggregation process leads to big and well-defined compact micelles with a uniform size and spherical-shape. The supramolecular

C-60 derivatives bearing either terminal alkyne or azide functional groups have been prepared and used as building blocks under the copper mediated Huisgen 1,3-dipolar cycloaddition conditions. In general, the reactivity of C60 toward azides does not significantly compete with the cycloaddition leading to the desired 1,2,3-triazole derivatives and good yields can be obtained when fullerene derivatives with reasonable Solubility are used as starting materials. The electrochemical properties of the new fullerene derivatives have also been investigated by cyclic voltammetry (CV) and Osteryoung Square Wave Voltammetry (OSWV). (C) 2008 Elsevier Ltd.
