“…By introducing fused rings into the polymer backbone, the sorting yield of HiPco SWNTs could be further enhanced through better pi-pi stacking. [94] In addition, we found that the n-type polymer P(NDI2OD-T2) (Figure 4a) could also enable the selective dispersion of semiconducting HiPco SWNTs. [95] SWNTs sorted using P(NDI2OD-T2) have larger diameters than P3DDT-sorted SWNTs (Figure 4f), likely as a result of the stronger interaction between the large aromatic core of the P(NDI20D-T2) backbone and larger-diameter SWNTs.…”

“…Conjugated polymers have also been extensively investigated for the sorting of HiPco SWNTs. [48,49,85,[90][91][92][93][94][95][96][97][98][99][100][101][102][103][104][105][106][107][108][109] Several of them can sort very specific chirality of SWNTs. Nish et al [48] and Chen et al [85] first observed that PFO (P1, Figure 3a) enriches small-diameter (8,6) SWNTs, whereas F8BT (P3, Figure 3a) enriches larger-diameter (10,5) SWNTs (Figure 3c,d, Table 2).…”

In the past decade, single-walled carbon nanotubes (SWNTs) have aroused great interest for electronic applications due to their extraordinary charge carrier mobility, mechanical flexibility, and solution processability. However, one of the key issues preventing the wide application of SWNTs in electronics is the need to separate semiconducting SWNTs from metallic SWNTs. Sorting semiconducting SWNTs using conjugated polymers is becoming a very promising SWNT sorting method due to its high-selectivity, high-yield and simplicity of execution. In this review, we summarized the parameters that can be used to tune the selectivity and sorting yield of semiconducting SWNTs, including polymer structure, solvent, polymer-to-SWNT ratio, sonication temperature and polymer molecular weight. We also reviewed the electronic applications enabled by these polymer-sorted semiconducting SWNTs inks such as transistors, logic gates, photodetectors, solar cells and 3D electronics.

Single-walled carbon nanotubes (SWNTs) possess unique electronic properties which make them promising materials for applications in both nano-electronics and flexible devices. Currently, no effective methods could large-scale synthesize SWNTs with single conductive properties. To obtain SWNTs with single conductive properties, a variety of separation methods have been developed. Among them, liquid phase separation approaches hold the promise for large scale production of the pure semiconducting SWNTs and have attracted intense interests. This paper summarized the mechanism and features of several liquid phase separation methods, including electrophoresis, density gradient centrifugation, chemical functionalization, gel chromatography and extraction. We also demonstrated the applications of the purified SWNTs in electronic devices. Finally, we discussed the challenges and opportunities for the separation of SWNTs.

“…1 Currently, the as-prepared SWCNTs contain mixtures of semiconducting (s-) and metallic (m-) components, which immensely hinder their applications in the electronics industry. 4 However, the available conjugated units required to obtain a high purity s-SWCNT dispersion were extremely limited until recently. Strategies based on post-synthesis exhibited enormous advantages in the large scale production of a high-purity s-SWCNT dispersion.…”

High-purity semiconducting single-walled carbon nanotubes (s-SWCNTs) are urgently needed in the development of beyond-silicon nanoelectronics. The utility of conjugated polymers to assist in the sorting of s-SWCNTs has attracted immense attention due to the simplicity of the sorting process and the high selectivity of conjugated polymers for s-SWCNTs. Rather than developing new types of conjugated polymers, this work provides a versatile and facile route for the sorting of s-SWCNTs with improved purity which is far beyond the sensitivity of a spectrometer.
