We use three alkyl-polyglycerol derivatives to suspend singlewalled 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.

Abstract
We use three alkyl-polyglycerol derivatives to suspend singlewalled 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
