International audience. Glycodendrimers based on aromatic cores have an amphiphilic character and have been reported to generate supramolecuar assemblies in water. A new group of glycodendrimers with an aromatic rod-like core were recently described as potent antagonists of DC-SIGN-mediated viral infections. A full characterization of the aggregation properties of these materials is presented here. The results show that these compounds exist mostly as monomers in water solution, in dynamic equilibrium with small aggregates (dimers or trimers). Larger aggregates observed by dynamic light scattering and transmission Electron Microscopy for some of the dendrimers are found to be portions of materials not fully solubilized and can be removed either by optimizing the dissolution protocol or by centrifugation of the samples.
