CoMoCat (6,5)-chirality enriched single-walled carbon nanotubes (SWCNTs) were dispersed with sodium dodecylbenzenesulfonate (SDBS). In brief, 500 µL 2 mg/mL SWCNTs/water suspension was added to 500 µL 2 % (m/v) SDBS solution, tip sonicated for 20 min with 40 % amplitude at 4 °C (Fisher ScientificTM Model 120 Sonic Dismembrator, 48 W) and centrifuged for 30 min at 21000 g. Then the supernatant was collected, transferred to a fresh tube and centrifuged again for 30 min at 21000 g. This step was repeated one more time, the supernatant was collected and the SWCNT/SDBS dispersion stored at 4 °C for the defect reaction.
