These intermediates can be captured by fullerene carbon cages for stabilization. In this paper, three C71H2 isomers were synthesized in situ in low-pressure benzene-acetylene-oxygen diffusion flame combustion. The results, which were unambiguously characterized by single-crystal X-ray diffraction, show that the three isomers are carbene addition products of D5h-C70 on different sites. The relative energies and stability of different C71H2 isomers are revealed by Ultraviolet-Visible (UV-Vis) absorption spectroscopy, in combination with theoretical calculations, in this work. Both the in situ capture and theoretical study of these C71H2 isomers in low-pressure combustion will provide more information regarding carbene additions to other fullerenes or other carbon clusters at high temperatures.<\/jats:p>","DOI":"10.3390\/nano12183087","type":"journal-article","created":{"date-parts":[[2022,9,7]],"date-time":"2022-09-07T01:51:57Z","timestamp":1662515517000},"page":"3087","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Carbene Addition Isomers of C70 formed in the Flame of Low-Pressure Combustion"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8196-8229","authenticated-orcid":false,"given":"Fang-Fang","family":"Xie","sequence":"first","affiliation":[{"name":"State Key Lab for Physical Chemistry of Solid Surfaces, Collaborative Innovation Center of Chemistry for Energy Materials, Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5201-0524","authenticated-orcid":false,"given":"Zuo-Chang","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Lab for Physical Chemistry of Solid Surfaces, Collaborative Innovation Center of Chemistry for Energy Materials, Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"You-Hui","family":"Wu","sequence":"additional","affiliation":[{"name":"State Key Lab for Physical Chemistry of Solid Surfaces, Collaborative Innovation Center of Chemistry for Energy Materials, Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Han-Rui","family":"Tian","sequence":"additional","affiliation":[{"name":"State Key Lab for Physical Chemistry of Solid Surfaces, Collaborative Innovation Center of Chemistry for Energy Materials, Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shun-Liu","family":"Deng","sequence":"additional","affiliation":[{"name":"State Key Lab for Physical Chemistry of Solid Surfaces, Collaborative Innovation Center of Chemistry for Energy Materials, Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Su-Yuan","family":"Xie","sequence":"additional","affiliation":[{"name":"State Key Lab for Physical Chemistry of Solid Surfaces, Collaborative Innovation Center of Chemistry for Energy Materials, Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lan-Sun","family":"Zheng","sequence":"additional","affiliation":[{"name":"State Key Lab for Physical Chemistry of Solid Surfaces, Collaborative Innovation Center of Chemistry for Energy Materials, Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"529","DOI":"10.1038\/329529a0","article-title":"The Stability of the Fullerenes Cn, with n = 24, 28, 32, 36, 50, 60 and 70","volume":"329","author":"Kroto","year":"1987","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"11016","DOI":"10.1021\/jp202885y","article-title":"Separation and Characterization of C70(C14H10) and C70(C5H6) from an Acetylene-Benzene-Oxygen Flame","volume":"115","author":"Weng","year":"2011","journal-title":"J.
