A Mixed-Extractor Strategy for Efficient Sorting of Semiconducting Single-Walled Carbon Nanotubes.

A general strategy for sorting semiconducting single-walled carbon nanotubes (s-SWNTs) with high efficiency using a mixed-extractor is reported. When the two extractors have a sufficient difference in binding energy with s-SWNTs, and skeleton flexibility, the mixture shows enhanced yield for sorting s-SWNTs. The strategy could be effective when applied to increase the sorting yield of other selective dispersion systems.
