“…Thus, the separation/purification of the s-SWCNTs on the basis of their chiralities is still one of the most important issues in the science and applications of carbon nanotubes. Many approaches have already been reported regarding s-SWCNT sorting − from as-synthesized SWCNTs, which are a mixture of s-SWCNTs and met-SWCNTs, while many of them are complex in the separation. For one-pot easy separation, we need to design a suitable solubilizer by an organic/polymer synthesis method.…”

The development of a facile method to sort semiconducting single-walled carbon nanotubes (s-SWCNTs) and their enantiomer recognition are still great challenges. We here describe a finding that a commercially available, safe, and cost-effective hydrophobic riboflavin analogue (riboflavin tetrabutyrate; RTB) efficiently sorts only s-SWCNTs by a one-pot method (bath-type sonication for 30 min followed by ultracentrifugation) and recognizes their enantiomers (left- and right-handed s-SWCNTs). The solubilization behavior of the SWCNTs strongly depends on the concentration of RTB; namely, with the decrease in the concentration of RTB, the s-SWCNT (n,m)-chiral selective sorting efficiency is enhanced. When using RTB = ∼0.4 mM (SWCNTs = 1 mg/3 mL toluene), two (n,m) chiralities of the s-SWCNTs with (n,m) = (8,6) and (8,7) were efficiently sorted. Furthermore, when using RTB = 0.5–1 mM, the SWCNT enantiomer recognition was observed. In addition, the X-ray photoelectron spectroscopic study revealed that the adsorbed RTB molecules on the s-SWCNTs were readily removed by simple rinsing with acetone to provide adsorbent-free pure s-SWCNTs. On the basis of the experimentally obtained data using Raman, photoluminescence, and visible–near-IR absorption spectroscopy techniques and computational density functional theory (DFT) approaches, we have revealed a possible mechanism for this unique s-SWCNT selective sorting and their enantiomer recognition. The supramolecular orientation of RTB into the helical superlattice with its own chirality provides a mechanism for chirality recognition. The study demonstrates one-pot sorting of s-SWCNTs and their enantiomer recognition using a cost-effective, safe molecule. Such a study is important for s-SWCNT separation science and its application in nanoscience and engineering areas.

Conjugated polymer sorting is recognized as an efficient and scalable method for the selective extraction of semiconducting single‐walled carbon nanotubes (s‐SWCNTs). However, this process typically requires the use of nonpolar and aromatic solvents as the dispersion medium, which are petroleum‐based and carry significant production hazards. Moreover, there is still potential for improving the efficiency of batch purification. Here, this study presents fluorene‐based conjugated polymer that integrates diamines containing ethylene glycol chains (ODA) as linkers within the main chain, to effectively extract s‐SWCNTs in bio‐renewable solvents. The introduction of ODA segments enhances the solubility in bio‐renewable solvents, facilitating effective wrapping of s‐SWCNTs in polar environments. Additionally, the ODA within the main chain enhances affinity to s‐SWCNTs, thereby contributing to increased yields and purity. The polymer achieves a high sorting yield of 55% and a purity of 99.6% in dispersion of s‐SWCNTs in 2‐Methyltetrahydrofuran. Thin‐film transistor arrays fabricated with sorted s‐SWCNTs solution through slot‐die coating exhibit average charge carrier mobilities of 20–23 cm2 V⁻¹ s⁻¹ and high on/off current ratios exceeding 105 together with high spatial uniformity. This study highlights the viability of bio‐renewable solvents in the sorting process, paving the way for the eco‐friendly approach to the purification of SWCNTs.
