Fluorescent chromophore functionalized single-wall carbon nanotubes with minimal alteration to their characteristic one-dimensional electronic statesElectronic supplementary information (ESI) available: Figs. S1, S3, and S5 are 1H-NMR spectra of 4-bromo-N-octadecyl-1,8-naphthalimide (II), N-octadecyl-4-piperazin-1-yl-1,8-naphthalimide (NA), and SWNT-NA, respectively. Figs. S2 and S4 are 13C-NMR spectra of 4-bromo-N-octadecyl-1,8-naphthalimide (II) and N-octadecyl-4-piperazin-1-yl-1,8-naphthalimide (NA), respectively. Fig. S6 is a surface pressure?surface area isotherm curve of SWNT-NA. See http://www.rsc.org/suppdata/jm/b3/b303885h/
