HPLC profile of (a) SWNT>(CF2)4 and (b) SWNT-(CF2)3CF3 monitored at 280 nm and gradient proportion of DOC concentration (wt%). Condition: column, ϕ10 × 200 mm; eluent, H2O containing 0.5 wt% SC, 1.0 wt% SDS, and X wt% DOC, where X corresponds to the values shown on the gradient; flow rate, 2 mL min−1. Absorption spectra of separated c SWNT>(CF2)4 and d SWNT-(CF2)3CF3 in D2O containing 1 wt% SC. CD spectra of separated e SWNT>(CF2)4 and f SWNT-(CF2)3CF3 (right) in D2O containing 1 wt% SC normalised by the E22 absorbance.
