Recent advances in the enrichment of semiconducting single-walled carbon nanotubes (s-SWCNTs), particularly via conjugated polymers extraction, allow for their wide applications with unique performances, especially for transistors and sensors. Both the low-cost enrichment and convenient device fabrication of s-SWCNTs have become high-priority and challenging tasks. In this study, we demonstrate that a dopamine functionalized thiophene-fluorene copolymer has the capability of selectively dispersing not only HiPco (0.7–1.2 nm) but also large diameter Arc-Discharge (1.2–1.7 nm) s-SWCNTs with a high efficiency and certain chirality in polar solvent tetrahydrofuran. Moreover, it is convenient to immobilize the obtained conjugated polymer wrapped s-SWCNTs on universal substrates, such as films and particles, based on the dopamine structure feature, which would facilitate the further development of their multifarious applications.

半导体单壁碳纳米管（s-SWCNT）富集的最新进展，特别是通过共轭聚合物萃取，使其具有广泛的应用，并具有独特的性能，特别是对于晶体管和传感器。s-SWCNT的低成本浓缩和方便的器件制造都已成为高度优先和具有挑战性的任务。在这项研究中，我们证明了多巴胺官能化的噻吩-芴共聚物不仅能够选择性分散HiPco（0.7-1.2 nm），而且还能高效分散大直径电弧放电（1.2-1.7 nm）s-SWCNT。在极性溶剂四氢呋喃中有一定的手性。此外，基于多巴胺结构特征，将获得的共轭聚合物包裹的s-SWCNTs固定在通用基材（如薄膜和颗粒）上非常方便，
