(a) 2D PL maps of pristine SWNT, SWNT/1Dz, and SWNT/2DzAr5 and (b) vis/NIR absorption spectra of pristine SWNTs (black), SWNT/1Dz (blue), and SWNT/2DzAr5 (red) in D₂O. [1Dz] = 0.40 μM and [2DzAr5] = 0.20 μM are used for the chemical modification. (c) PL area ratios of E₁₁²* to E₁₁ (A(E₁₁²*)/A(E₁₁)) as a function of the diazonium concentrations for SWNT/2DzAr5 (blue dot) and SWNT/1Dz (black dot). (d) Excitation spectra for E₁₁²* (green) and E₁₁* (red) and vis/NIR absorption spectrum (blue) of SWNT/2DzAr5 in D₂O. [2DzAr5] = 0.40 μM was used for the chemical modification. (e) PL spectra of SWNT/2DzAr5 before (black) and after (red) dialysis against a 0.2 wt% (5.7 mM) SDBS solution: λ_ex = 570 nm and 980 nm.
