In 2022,Wu, Yimin; Zhang, Ling; Ma, Fudong; Ding, Tao; Obolda, Ablikim published an article in Designed Monomers and Polymers. The title of the article was 《Synthesis of carbazole-based dendritic conjugated polymer: dual channel optical probe for detection of iodine (-) and mercury (2+)》.Recommanded Product: 6825-20-3 The author mentioned the following in the article:
A new type of carbazole-based blue-emitting dendritic conjugated polymer, poly[(9,9-dioctyl)-2,7-fluorene-co-4,4′,4”-triphenylamine-co-9-(4-(9H-carbazol-9-yl)butyl)-3,6-carbazole](P), was successfully synthesized by Suzuki coupling reaction. Chem. structures of monomers and polymer were verified by FI-IR and 1HNMR characterizations. We found that polymer showed a special selectivity and high sensitivity for I-. With the addition of I-, the fluorescent polymer solution was obviously quenched. The polymer showed a special detection effect on I-. However, the fluorescent polymer was obviously restored when Hg2+ was added to the P/I- system due to the large complexation between I- and Hg2+. The anti-interference experiments of probe P/I- showed that other background cations have a slight influence on detecting Hg2+, and the calculated detection limit of Hg2+ reached 9.7 x 10-8 M, which could be a potential application for a two-channel cyclic detection of I- and Hg2+. Addnl., it was found that the theor. values were in agreement with the exptl. data. In the experiment, the researchers used many compounds, for example, 3,6-Dibromo-9H-carbazole(cas: 6825-20-3Recommanded Product: 6825-20-3)
3,6-Dibromo-9H-carbazole(cas: 6825-20-3) is used as a reagent in the synthesis of P7C3-A20 which is a potent neuroprotective agent. And it has been used in the preparation of N-(2-hydroxyethyl)-3,6-dibromocarbazole.Recommanded Product: 6825-20-3
