In this paper, scandium (III) trifluoromethanesulfonate was used as a catalyst to successfully prepare covalent organic framework (COF) nanospheres linked by imines at room temperature. The COF nanospheres were characterized by XRD, SEM, TEM, FT-IR, UV-Vis and BET. The results show that COF nanospheres have rough surfaces and a large number of mesoporous structures, which greatly increase the active sites on the surface of the sensing material and enhance the gas sensing performance. The sensing results showed that the prepared imine-conjugated COF nanospheres exhibited a good response\u2013recovery ability for 10 consecutive response\u2013recovery cycles for ethylene glycol at room temperature and had a theoretical detection limit of 40 ppb. In addition, the responses of COF nanospheres to nearly 20 interfering gases, including HCl, HNO3, phenol, formaldehyde and aniline, are relatively low compared to the response to ethylene glycol, indicating that the COF nanospheres have high selectivity towards ethylene glycol. The COF nanospheres show good sensitivity and selectivity for the detection of ethylene glycol, which should be attributed to the large specific surface area, hydrogen bonding interactions, and high defects. This work provides an effective method for the detection of ethylene glycol and expands the application field of COF materials.<\/jats:p>","DOI":"10.3390\/nano13243103","type":"journal-article","created":{"date-parts":[[2023,12,11]],"date-time":"2023-12-11T11:24:43Z","timestamp":1702293883000},"page":"3103","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["High-Performance Ethylene Glycol Sensor Based on Imine Covalent Organic Frameworks"],"prefix":"10.3390","volume":"13","author":[{"given":"Shiwei","family":"Liu","sequence":"first","affiliation":[{"name":"Xinjiang Key Laboratory of Solid-State Physics and Devices, Urumqi 830046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guojie","family":"Zhang","sequence":"additional","affiliation":[{"name":"Xinjiang Key Laboratory of Solid-State Physics and Devices, Urumqi 830046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiyu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Xinjiang Key Laboratory of Solid-State Physics and Devices, Urumqi 830046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ning","family":"Tian","sequence":"additional","affiliation":[{"name":"Xinjiang Key Laboratory of Solid-State Physics and Devices, Urumqi 830046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qihua","family":"Sun","sequence":"additional","affiliation":[{"name":"Xinjiang Key Laboratory of Solid-State Physics and Devices, Urumqi 830046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaofeng","family":"Wu","sequence":"additional","affiliation":[{"name":"Xinjiang Key Laboratory of Solid-State Physics and Devices, Urumqi 830046, China"},{"name":"School of Physics Science and Technology, Xinjiang University, Urumqi 830046, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,8]]},"reference":[{"key":"ref_1","first-page":"362","article-title":"Accuracy of a Glycerol Dehydrogenase Assay for Ethylene Glycol Detection","volume":"19","author":"Filip","year":"2023","journal-title":"J.
