Fig. 4: Submilligram-scale separation of single-chirality species from high-concentration G-SWCNTs.

a Optical absorption spectra and b statistical purity distribution of the separated single-chirality SWCNTs. c Photograph of the solutions of high-purity single-chirality SWCNTs. From left to right, the solutions correspond to the (8, 4), (6, 4), (7, 6), (9, 1), (7, 3), (7, 5), (9, 4), (6, 5) and (10, 3) species.
