Detecting and quantifying Al3+ is vital for both chemistry and biology. A new Schiff-based fluorescent turn-on sensor (probe L) for the selective detection of the Al3+ ion was synthesized by coupling 2-hydroxy-1-naphthaldehyde and 2-aminoisoindoline-1,3-dione, and the structure was characterized by nuclear magnetic resonance spectra. The probe L exhibited an excellent selective and sensitive response to the Al3+ ion over other metal ions in DMSO-H2O (1:9 v\/v). Fluorescence quantification revealed that probe L was promising for the detection and accumulation of Al3+. Treating rice seedlings with Al3+ at 25\u2013200 \u03bcM inhibited their growth. Al3+ treatment produced reactive oxygen species in rice roots. Practical applications of the fluorescent probe for the quantification of Al3+ in water samples and rice seedlings are demonstrated. Detecting the Al3+ ion with the probe L is easy and a potential alternative to existing analytical methods. The method can be used for detecting the Al3+ content of aqueous solution and plant systems. The novel fluorescent probe L has good potential for monitoring Al3+ content in the environment and biological systems.<\/jats:p>","DOI":"10.3390\/s19030623","type":"journal-article","created":{"date-parts":[[2019,2,1]],"date-time":"2019-02-01T11:19:58Z","timestamp":1549019998000},"page":"623","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["A Highly Selective and Sensitive Fluorescent Chemosensor for Detecting Al3+ Ion in Aqueous Solution and Plant Systems"],"prefix":"10.3390","volume":"19","author":[{"given":"Chia-Lin","family":"Li","sequence":"first","affiliation":[{"name":"Department of Chemistry, National Changhua University of Education, Changhua 50058, Taiwan"}]},{"given":"Ping-Hsuan","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Chemistry, National Changhua University of Education, Changhua 50058, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5482-8837","authenticated-orcid":false,"given":"Shih-Feng","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Biology, National Changhua University of Education, Changhua 50058, Taiwan"}]},{"given":"An-Tai","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Chemistry, National Changhua University of Education, Changhua 50058, Taiwan"}]}],"member":"1968","published-online":{"date-parts":[[2019,2,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"459","DOI":"10.1146\/annurev.arplant.55.031903.141655","article-title":"How do crop plants tolerate acid soils?
