In 2017,Feng, Liheng; Deng, Yang; Wang, Xiaoju; Liu, Mingguang published 《Polymer fluorescent probe for Hg(II) with thiophene, benzothiazole and quinoline groups》.Sensors and Actuators, B: Chemical published the findings.Application of 626-40-4 The information in the text is summarized as follows:
A facile polymer consisted of quinoline, thiophene and benzothiazole groups was designed and synthesized by Suzuki coupling reaction. The study of photophys. property indicated that the polymer was a red light emitter with maximum absorption (490 nm) and emission (610 nm) peaks. The assays of thermal gravimetric anal. (TGA) and cyclic voltammetry (CV) revealed that the polymer possesses good thermal (Td, 228°C) and electrochem. properties. The exptl. data based on the cyclic voltammetry were in good agreement with the results of theor. calculations The sensing processes of the polymer to metal ions were investigated by UV-vis absorption and fluorescence emission spectra. The results showed that the polymer had high selectivity and sensitivity for Hg(II) ions with an obvious “”turn-on”” fluorescence in the presence of Hg(II). Noticeably, the polymer as a fluorescence probe can be applied in the detection in practical samples. The attribution of the work lies in providing a new strategy for design and application of polymer probes in anal. and testing fields. In the experiment, the researchers used 3,5-Dibromoaniline(cas: 626-40-4Application of 626-40-4)
3,5-Dibromoaniline(cas: 626-40-4) belongs to anime. The methylamines occur in small amounts in some plants. Many polyfunctional amines (i.e., those having other functional groups in the molecule) occur as alkaloids in plants—for example, mescaline, 2-(3,4,5-trimethoxyphenyl)ethylamine; the cyclic amines nicotine, atropine, morphine, and cocaine; and the quaternary salt choline, N-(2-hydroxyethyl)trimethylammonium chloride, which is present in nerve synapses and in plant and animal cells.Application of 626-40-4
