We thank Prof. H. Furuta of Kyushu University for the use of a Horiba Spex Fluorolog-NIR spectrofluorometer and Prof. S. Maruyama and Mr. Y. Miyauchi of The University of Tokyo for the mapping of a near-IR photoluminescence spectrum. This work was in part performed by the support of the Grant-in-Aids from the Ministry of Education, Science, Sports and Culture, Japan.

N2 - We report here the finding by means of visible-near IR absorption and near-IR fluorescence spectroscopies and atomic force microscopy that a total aromatic polyimide has a high potential to solubilize single-walled carbon nanotubes (SWNTs) individually in organic solutions. The solutions contained SWNTs having (7, 6), (7, 5), (8, 4), (9, 5) and (8, 6) indices. With the increasing concentrations of SWNTs, the solutions became viscous and then changed to gels that exhibited characteristic spectral features of individually dissolved SWNTs.
