摘要

Selective sorting of semiconducting single-walled carbon nanotubes (SWNTs) of single chirality is critical for constructing electronic nanodevices with high performance. Nevertheless, trade-off between yield and chirality purity often exists in conventional SWNTs sorting processes. To solve this problem, we present an extremely facile method for enriching SWNTs with both high yield and high chiral selectivity. Simply by using a solvent mixed with toluene and chlorobenzene at certain volume ratio, the sorting yield of (6,5)SWNTs was largely enhanced via polymer extraction, while the chirality purity of sorted SWNTs could be kept high as well. We further proved that the sorting efficiency would not be lowered even after multiple extractions, while the chirality selectivity of the obtained SWNTs was dependent on exact ratio between the two solvents. Solvent polarity-controlled polymer (or solvent molecule)-SWNTs interaction was believed responsible for our results, which was later successfully testified by molecular dynamics simulations. Our proposed strategy will simplify the selecting process of single chiral SWNTs and benefit the optimization of SWNTs-integrated devices in near future.
