摘要：

We use three alkyl-polyglycerol derivatives to suspend single-walled carbon nanotubes. The molecules differ by the aromatic moieties between the alkyl tail and the polyglycerol head. The suspended nanotubes are analysed by photoluminescence spectroscopy. We observe a dependence of the luminescence intensity and hence nanotube abundance on the aromatic moieties. Interestingly, the strength of interaction depends on the nanotube families. [GRAPHICS] Molecular sketch of the studied surfactants. (c) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
