Spectroscopic analysis and atomic force microscopy ͑AFM͒ phase imaging studies show self-assembly of phenosafranin ͑PSF͒ to multiwalled carbon nanotubes ͑MWNTs͒. The shift in absorption spectra is associated with charge transfer of valence electrons from PSF to electron accepting sites on the MWNTs. The Raman-active disorder modes are used to fingerprint PSF attachment to MWNTs via defect states. AFM phase imaging was used to obtain a molecular topographic visual confirmation of PSF attached to
