Nanorods versus nanovesicles from amphiphilic dendrofullerenes

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.Financial support by the MICINN of Spain (CTQ2008-00795/BQU, CTQ2008-01694), the CAM (MADRISOLAR-2 S2009/PPQ-1533), and Consolider-Ingenio CSD2007-00010, Nanociencia Molecular), and the EU (FUNMOL FP7-212942-1) is greatly appreciated.
