TNP is an electron-deficient and negative molecule, which is captured by PCP6 via electrostatic interactions and \u03c0\u2013\u03c0 interactions. Therefore, a selective and sensitive fluorescence probe for TNP detection is developed. It has a low detection limit of 0.0035 \u03bcM (S\/N = 3) and a wider linear response of 0.01\u20135.0 and 5.0\u2013125.0 for TNP. The sensing platform is also used to test TNP in two water and soil samples with satisfying results. This suggests that this approach has potential applications for the determination of TNP.<\/jats:p>","DOI":"10.3390\/s19010091","type":"journal-article","created":{"date-parts":[[2018,12,28]],"date-time":"2018-12-28T11:52:42Z","timestamp":1545997962000},"page":"91","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["A Fluorescence Sensing Determination of 2,4,6-Trinitrophenol Based on Cationic Water-Soluble Pillar[6]arene Graphene Nanocomposite"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6531-0251","authenticated-orcid":false,"given":"Xiaoping","family":"Tan","sequence":"first","affiliation":[{"name":"Key Lab of Inorganic Special Functional Materials, Chongqing Municipal Education Commission, School of Chemistry and Chemical Engineering, Yangtze Normal University, Chongqing 408100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tingying","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Lab of Inorganic Special Functional Materials, Chongqing Municipal Education Commission, School of Chemistry and Chemical Engineering, Yangtze Normal University, Chongqing 408100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenjie","family":"Zeng","sequence":"additional","affiliation":[{"name":"Key Lab of Inorganic Special Functional Materials, Chongqing Municipal Education Commission, School of Chemistry and Chemical Engineering, Yangtze Normal University, Chongqing 408100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuhua","family":"He","sequence":"additional","affiliation":[{"name":"Key Lab of Inorganic Special Functional Materials, Chongqing Municipal Education Commission, School of Chemistry and Chemical Engineering, Yangtze Normal University, Chongqing 408100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xi","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Lab of Inorganic Special Functional Materials, Chongqing Municipal Education Commission, School of Chemistry and Chemical Engineering, Yangtze Normal University, Chongqing 408100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hexiang","family":"Tian","sequence":"additional","affiliation":[{"name":"Key Lab of Inorganic Special Functional Materials, Chongqing Municipal Education Commission, School of Chemistry and Chemical Engineering, Yangtze Normal University, Chongqing 408100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianwei","family":"Shi","sequence":"additional","affiliation":[{"name":"Key Lab of Inorganic Special Functional Materials, Chongqing Municipal Education Commission, School of Chemistry and Chemical Engineering, Yangtze Normal University, Chongqing 408100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tuanwu","family":"Cao","sequence":"additional","affiliation":[{"name":"Key Lab of Inorganic Special Functional Materials, Chongqing Municipal Education Commission, School of Chemistry and Chemical Engineering, Yangtze Normal University, Chongqing 408100, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1261","DOI":"10.1039\/C1CS15173H","article-title":"Optical chemosensors and reagents to detect explosives","volume":"41","author":"Salinas","year":"2012","journal-title":"Chem.
