The fluorescence spectra of the target compounds were recorded. The spectra show that most of the title compounds glow green with \u03bbmaxem of 500\u2013517 nm, while compounds 5r, 5s, 5u, and 5l (compounds named by authors) glow violet with \u03bbmaxem of 381\u2013443 nm. Moreover, the herbicidal and antifungal activities of the synthesized compounds were evaluated for their potential use as pesticides. The results indicate that compound 5f against the caulis of Amaranthus retroflexus and compounds 5j and 5l against the taproot of Digitaria sanguinalis are equivalent to the commercial herbicide Acetochlor. Nine of the title compounds are more antifungal than commercial fungicide Carbendazim against Botrytis cinerea.<\/jats:p>","DOI":"10.3390\/molecules23030600","type":"journal-article","created":{"date-parts":[[2018,3,7]],"date-time":"2018-03-07T12:55:23Z","timestamp":1520427323000},"page":"600","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Novel Trifluoromethylcoumarinyl Urea Derivatives: Synthesis, Characterization, Fluorescence, and Bioactivity"],"prefix":"10.3390","volume":"23","author":[{"given":"Lili","family":"Qiao","sequence":"first","affiliation":[{"name":"Research Center of Agro-bionic Engineering & Tech. of Shandong Province, College of Chemistry & Pharm., Qingdao Agricultural University, Qingdao 266109, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuanghong","family":"Hao","sequence":"additional","affiliation":[{"name":"Research Center of Agro-bionic Engineering & Tech. of Shandong Province, College of Chemistry & Pharm., Qingdao Agricultural University, Qingdao 266109, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,3,7]]},"reference":[{"key":"ref_1","first-page":"379","article-title":"Synthesis and in-vitro antibacterial activity of some new urea, thiourea and thiosemicarbazide derivatives","volume":"4","author":"Umadevi","year":"2012","journal-title":"Int.
