Abstract: | 以環三聚藜烴為基礎的分子籠可與市售之Sc3N@C80 形成準囚籠錯合物,藉此有效提升Sc3N@C80 在氘-氯仿中的溶解度。該金屬富勒烯的兩結構異構物 (Sc3N@D5h-C80 與 Sc3N@Ih-C80) 被包覆於分子籠內後,可在1H 及13C NMR 光譜中表現不同的特徵訊號,無須使用13C-濃化的樣品即可直接鑑定其結構異構物。 A cyclotriveratrylene-based molecular cage forms hemicarceplexes that significantly increase the solubility of commercially available Sc3N@C80 in CDCl3. When incarcerated within the molecular cage, the two structural isomers of this metallofullerene, Sc3N@D5h-C80 and Sc3N@Ih-C80, displayed characteristic signals in both 1H and 13C NMR spectra, allowing direct identification of each isomer without the need to enrich the sample with 13C atoms. |
