N,N\u2019-Di((anthracen-9-yl)-methylene) thio-carbonohydrazide showed sensitive and selective binding ability for acetate ion among the studied anions. The presence of other competitive anions including F\u2212, H2PO4\u2212, Cl\u2212, Br\u2212 and I\u2212 did not interfere with the strong binding ability. The mechanism of the  host-guest interaction was through multiple hydrogen bonds due to the conformational complementarity and higher basicity. A theoretical investigation explained that  intra-molecular hydrogen bonds existed in the compound which could strengthen the anion binding ability. In addition, molecular frontier orbitals in molecular interplay were introduced in order to explain the red-shift phenomenon in the host-guest interaction process. Compounds based on thiourea and anthracene derivatives can thus be used as a chemosensor for detecting acetate ion in environmental and pharmaceutical samples.<\/jats:p>","DOI":"10.3390\/s151128166","type":"journal-article","created":{"date-parts":[[2015,11,6]],"date-time":"2015-11-06T11:12:15Z","timestamp":1446808335000},"page":"28166-28176","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["The Synthesis and Anion Recognition Property of  Symmetrical Chemosensors Involving Thiourea Groups:  Theory and Experiments"],"prefix":"10.3390","volume":"15","author":[{"given":"Xuefang","family":"Shang","sequence":"first","affiliation":[{"name":"Department of Chemistry, Xinxiang Medical University, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenhua","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Xinxiang Medical University, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiajia","family":"Fu","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Xinxiang Medical University, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peipei","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Xinxiang Medical University, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiufang","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Nankai University, Tianjin 300071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2015,11,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8038","DOI":"10.1021\/acs.chemrev.5b00099","article-title":"Applications of supramolecular anion recognition","volume":"115","author":"Busschaert","year":"2015","journal-title":"Chem.
