It used 1,10-phenanthroline moiety as a fluorescent signaling site and binding site, with optically active \u03b2-amino acids as a chiral barrier site. Notably, the optically active \u03b2-amino acids were obtained by a Lewis base catalyzed hydrosilylation of \u03b2-enamino esters according to our former work. The chiral sensor has been used to conduct the enantioselective recognition of chiral mono and dicarboxylic acids derivatives. Using this fluorescent sensor, a moderate \u201cturn-off\u201d fluorescence-diminishment response towards enantiomer of tartaric acids, and proline was observed. It found that l-enantiomers quench the chiral fluorescence sensor more efficiently than d-enantiomers due to the absolute configuration of the \u03b2-amino acid.<\/jats:p>","DOI":"10.3390\/s150510723","type":"journal-article","created":{"date-parts":[[2015,5,6]],"date-time":"2015-05-06T10:58:41Z","timestamp":1430909921000},"page":"10723-10733","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Enantioselective Recognition of Chiral Carboxylic Acids by a \u03b2-Amino Acid and 1,10-Phenanthroline Based Chiral Fluorescent Sensor"],"prefix":"10.3390","volume":"15","author":[{"given":"Yonghong","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory of Petroleum and Gas Fine Chemicals of Ministry of Education,  School of Chemistry and Chemical Engineering, Xinjiang University, Urumqi 830046, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fangzhi","family":"Hu","sequence":"additional","affiliation":[{"name":"Chengdu Institute of Organic Chemistry, Chinese Academy of Sciences, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Wang","sequence":"additional","affiliation":[{"name":"Physics and Chemistry Detecting Center, Xinjiang University, Urumqi 830046, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaomei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Chengdu Institute of Organic Chemistry, Chinese Academy of Sciences, Chengdu 610041, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chenjiang","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Petroleum and Gas Fine Chemicals of Ministry of Education,  School of Chemistry and Chemical Engineering, Xinjiang University, Urumqi 830046, China"},{"name":"Physics and Chemistry Detecting Center, Xinjiang University, Urumqi 830046, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,5,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2405","DOI":"10.1021\/cr970463w","article-title":"1,1'-binaphthyl dimers, oligomers, and polymers: Molecular recognition, asymmetric catalysis, and new materials","volume":"98","author":"Pu","year":"1998","journal-title":"Chem.
