Dye molecules (anthracene derivatives) are observed to strongly adsorb single-walled carbon nanotubes (SWNTs). The adsorption coverage of anthracene on SWNTs varied with the aromatic ring substituents. red shifts emission peaks absorptive adduct appear depend energy level lowest unoccupied molecular orbital (LUMO) adsorbate, consistent by a charge-transfer interaction, in which SWNT is electron donor and acceptor. adducts can be displaced pyrene.
