In this work, we demonstrate that pyridine\u2010derived carbon nitride nanothread samples can be intercalated with potassium to produce reduced carbon nitride nanothreads that can be readily dispersed in polar organic solvents such as dimethyl sulfoxide. Atomic force microscopy of thin films produced from these dispersions reveals thread\u2010like objects as narrow as 0.6 nm in height, suggesting exfoliation and dispersion into individualized threads and small bundles. The individualized nanothreads emit blue\/green luminescence, suggesting potential utility in optoelectronic applications. Remarkably, the temperature\u2010dependent conductivity of a thin film of nanothreads shows weakly semiconducting behavior, falling only \u223c40% from room temperature to 2 K. The reductive dissolution approach reported in this work greatly improves the processability of as\u2010grown nanothread materials, thus opening opportunities for single\u2010nanothread characterization, post\u2010synthetic functionalization, thin film fabrication, and the production of nanothread composites.<\/jats:p>","DOI":"10.1002\/smll.74445","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T07:54:17Z","timestamp":1785743657000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Individualization and Purification of Carbon Nanothreads"],"prefix":"10.1002","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5562-1125","authenticated-orcid":false,"given":"George","family":"Bepete","sequence":"first","affiliation":[{"name":"Department of Physics The Pennsylvania State University  University Park Pennsylvania USA"},{"name":"Department of Chemistry The Pennsylvania State University  University Park Pennsylvania USA"},{"name":"Center for 2\u2010Dimensional and Layered Materials Centre for Atomically Thin Multifunctional Coatings The Pennsylvania State University  University Park Pennsylvania USA"},{"name":"Materials Research Institute The Pennsylvania State University  University Park Pennsylvania USA"},{"name":"Department of Chemical and Materials Engineering Centre for NanoScience Research (CeNSR) Concordia University  Montreal Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sikai","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Chemistry The Pennsylvania State University  University Park Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bohan","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Physics The Pennsylvania State University  University Park Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c1mbar E.
