This paper presents the new selenium derivatives obtained by a covalent functionalization of brominated multi-walled carbon nanotubes (MWCNTs). The synthesis was carried out in mild conditions (3 days at room temperature), and was additionally assisted with ultrasound. After a two-stage purification, the obtained products were identified and characterized by the following methods: scanning and transmission electron microscopy imaging (SEM and TEM), energy dispersive X-ray microanalysis (EDX), X-ray photoelectron spectroscopy (XPS), Raman and nuclear magnetic resonance (NMR), and X-ray diffraction (XRD). In the selenium derivatives of carbon nanotubes, the content of selenium and phosphorus reached 14 and 4.2 wt%, respectively.<\/jats:p>","DOI":"10.3390\/ijms24043299","type":"journal-article","created":{"date-parts":[[2023,2,8]],"date-time":"2023-02-08T03:01:45Z","timestamp":1675825305000},"page":"3299","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Synthesis and Structural Studies of New Selenium Derivatives Based on Covalent Functionalization of MWCNTs"],"prefix":"10.3390","volume":"24","author":[{"given":"Sandra","family":"\u017barska","sequence":"first","affiliation":[{"name":"Institute of Chemistry, Faculty of Science and Technology, Jan Dlugosz University in Czestochowa, 13\/15 Armii Krajowej Ave., 42-200 Czestochowa, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1291-4040","authenticated-orcid":false,"given":"Rafa\u0142","family":"Szukiewicz","sequence":"additional","affiliation":[{"name":"Faculty of Physics and Astronomy, Institute of Experimental Physics, University of Wroclaw, 50-204 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8993-5552","authenticated-orcid":false,"given":"Sergiu","family":"Coseri","sequence":"additional","affiliation":[{"name":"Polyaddition and Photochemistry Department, Petru Poni Institute of Macromolecular Chemistry, 41A Grigore Ghica Voda Alley, 700487 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1893-2706","authenticated-orcid":false,"given":"Volodymyr","family":"Pavlyuk","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Faculty of Science and Technology, Jan Dlugosz University in Czestochowa, 13\/15 Armii Krajowej Ave., 42-200 Czestochowa, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2361-6401","authenticated-orcid":false,"given":"Dorota","family":"Krasowska","sequence":"additional","affiliation":[{"name":"Division of Organic Chemistry, Centre of Molecular and Macromolecular Studies, Polish Academy of Sciences, 112 Sienkiewicza Str., 90-001 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wojciech","family":"Ciesielski","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Faculty of Science and Technology, Jan Dlugosz University in Czestochowa, 13\/15 Armii Krajowej Ave., 42-200 Czestochowa, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Mukhopadhyay, S.M.
