Both 1 and 2 exhibit aggregation-induced phosphorescence emission (AIPE) properties in THF\/H2O. Among them, 2 is extremely sensitive for detecting PA with a limit of detection of 0.15 \u03bcM in THF\/H2O. Furthermore, the selectivity for PA is significantly higher compared to other analytes, enabling the efficient detection of PA in four common water samples. The density functional theory calculations and the spectroscopic results confirm that the sensing mechanism is photo-induced electron transfer (PET).<\/jats:p>","DOI":"10.3390\/s24134074","type":"journal-article","created":{"date-parts":[[2024,6,24]],"date-time":"2024-06-24T06:59:58Z","timestamp":1719212398000},"page":"4074","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Carbazolyl-Modified Neutral Ir(III) Complexes for Efficient Detection of Picric Acid in Aqueous Media"],"prefix":"10.3390","volume":"24","author":[{"given":"Jiangchao","family":"Xu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Fine Chemicals, Frontier Science Center for Smart Materials, School of Chemical Engineering, Dalian University of Technology, Linggong Road 2, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liyan","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Fine Chemicals, Frontier Science Center for Smart Materials, School of Chemical Engineering, Dalian University of Technology, Linggong Road 2, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yusheng","family":"Shi","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Fine Chemicals, Frontier Science Center for Smart Materials, School of Chemical Engineering, Dalian University of Technology, Linggong Road 2, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3521-8483","authenticated-orcid":false,"given":"Chun","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Fine Chemicals, Frontier Science Center for Smart Materials, School of Chemical Engineering, Dalian University of Technology, Linggong Road 2, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1740","DOI":"10.1039\/b105159h","article-title":"Aggregation-induced emission of 1-methyl-1,2,3,4,5-pentaphenylsilole","volume":"18","author":"Luo","year":"2001","journal-title":"Chem.
