Abstract

The effect of alkali metal counterions on the aggregation behaviour of an anionic perylene dye has been investigated by absorption and emission spectroscopy. In the presence of Na+ aggregation is enhanced leading to a decreased surfactant capability for the dispersion of carbon nanotubes.
