Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 375-72-4, Name is 1,1,2,2,3,3,4,4,4-Nonafluorobutane-1-sulfonyl fluoride, SMILES is O=S(C(F)(F)C(F)(F)C(F)(F)C(F)(F)F)(F)=O, in an article , author is Peng, Shanxi, once mentioned of 375-72-4, Computed Properties of C4F10O2S.
A photochromic diarylethene-functionalized fluorescent probe for Cd2+ and Zn2+ detections
A novel bifunctional chemosensor 10 constructed with diarylethene and pyridazine unit has been designed and synthesized with excellent photochromic properties upon UV/Vis radiation. The chemosensor 10 shows prominent selectivity and high sensitivity for Cd2+ and Zn2+ by obvious fluorescent enhancement with a low detection limit in water-acetonitrile solution (v((water)):v((acetonitrile)) = 1:9). The chemosensor 10 could be utilized as a fluorescent sensor for Cd2+ with a limit of detection (LOD) of 2.3 x 10(-6) M. With the presence of Zn2+, the fluorescence of the generated zinc complex enhances remarkably and the limit of detection (LOD) for Zn2+ is calculated to be 1.1 x 10(-5) M by Job’s plot titrations. A logic circuit of this chemosensor 10 has been constructed with the input signals of UV and visible light, Cd2+ (or Zn2+) and EDTA and the output signal of the emission intensity. In addition, the concentrations of Cd2+ or Zn2+ in real water are detected quickly and conveniently by this chemosensor. (C) 2020 Elsevier Ltd. All rights reserved.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 375-72-4, you can contact me at any time and look forward to more communication. Computed Properties of C4F10O2S.
