| Title | A simple and efficient colorimetric anion sensor based on a thiourea group in DMSO and DMSO-water and its real-life application. | | Author(s) | Shao J, Lin H, Lin HK | | Institution | Department of Chemistry, Nankai University, Tianjin 300071, People's Republic of China. | | Source | Talanta 2008 May 30; 75(4):1015-20. | | Abstract | An efficient colorimetric sensor with a thiourea moiety as binding sites and p-nitrophenylhydrazine as a signaling unit has been synthesized by only one single-step procedure. Selectivity for anions with the distinct geometry (tetrahedral, trigonal planar and spherical) has been investigated in dry DMSO and even in DMSO/H(2)O (95:5, v/v) solutions through the naked-eye experiment, UV-vis titration and (1)H NMR titration techniques. In particular, the fluoride of toothpaste can be detected qualitatively by the sensor 1. | | Language | eng | | Pub Type(s) | Journal Article
