Aqueous dispersions of carbon nanotubes (CNTs) were obtained by noncovalent adsorption of an azobenzene derivative carrying polyglycerol dendric structures. UV/Vis absorption spectra and photoluminescence maps were recorded to confirm successful nanotube debundling and suspension. Comparison to dispersion of nanotubes using sodium dodecyl sulfate (SDS) revealed shifts of the nanotube E 22 excitation peaks from 28 to 67 meV as well as shifts from 21 to 37 meV of the E 11 emission peaks.
