The formation of cage 1 was characterized and confirmed by NMR spectroscopy, mass spectrometry, and theoretical calculations. The yield of cage 1 could be controlled by tuning the reaction conditions, such as the precursor concentration. Interestingly, the addition of 10 equiv of Cd2+ relative to cage 1 could increase the fluorescence almost seven-fold. 1H NMR and fluorescence experiments indicating fluorescence enhancement may be caused by the decomposition of cage 1. Such a high selectivity toward Cd2+ implies that the cage could potentially be employed in cadmium detection.<\/jats:p>","DOI":"10.3390\/molecules28041841","type":"journal-article","created":{"date-parts":[[2023,2,16]],"date-time":"2023-02-16T01:36:52Z","timestamp":1676511412000},"page":"1841","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Benzothiadiazole-Based Self-Assembled Cage for Cadmium Detection"],"prefix":"10.3390","volume":"28","author":[{"given":"Zong-Cheng","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Biology and Chemistry, Hunan University of Science and Engineering, Yongzhou 415199, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying-Zi","family":"Tan","sequence":"additional","affiliation":[{"name":"Department of Biology and Chemistry, Hunan University of Science and Engineering, Yongzhou 415199, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hui","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Biology and Chemistry, Hunan University of Science and Engineering, Yongzhou 415199, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen-Hu","family":"Bao","sequence":"additional","affiliation":[{"name":"Department of Biology and Chemistry, Hunan University of Science and Engineering, Yongzhou 415199, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lin-Li","family":"Tang","sequence":"additional","affiliation":[{"name":"Department of Biology and Chemistry, Hunan University of Science and Engineering, Yongzhou 415199, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fei","family":"Zeng","sequence":"additional","affiliation":[{"name":"Department of Biology and Chemistry, Hunan University of Science and Engineering, Yongzhou 415199, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8542","DOI":"10.1021\/cr400673y","article-title":"Multiporphyrinic Cages: Architectures and Functions","volume":"114","author":"Durot","year":"2014","journal-title":"Chem.
