(a) UV–VIS spectrum of SWCNTs suspended by PFO-3DDT. (b) Excitation-emission PL map of SWCNTs suspended by PFO-3DDT ((6,4) and (9,1) SWCNTs are not visible as they emit outside of the measurement range). (c) The influence of molecular characteristics of the synthesized PFO batches on the optical absorbance spectra of SWCNTs suspended with PFO. *The polymer with the highest Mw (49.74 kg/mol) refers to Pd(PPh3)4–driven reaction, which is shown here as a reference. All the other polymers were obtained using PdNPs/NiNWs nanocatalyst. (d) Excitation-emission PL map of extracted (7,5) SWCNTs using PFO synthesized using the specified conditions (Table 1, entry 13).
