The article conveys some information:
A novel C2-sym. ratiometric fluorescence and colorimetric cyanide (CN-) sensor 1 (I) based on a phenol-bisthiazolopyridine hybrid was synthesized and characterized. Among the various screened anions, this chromogenic receptor 1 showed only a distinct visible color change from colorless to yellow and blue to green fluorescence toward CN- in both pure methanol and aqueous methanol. The ”turn-on” ratiometric fluorescence (emission shift = 95 nm) and colorimetric (absorbance shift = 45 nm) detection of CN- can be attributed to the deprotonation of the OH groups of 1, as evidenced by OH- and 1H NMR experiments The binding mode of 1 with CN- was determined to be a 1 : 1 stoichiometry through a Job plot. Probe 1 was also highly sensitive (LOD = 75 nM) as measured by ratiometric fluorescence (I420/I515 nm) methods. Moreover, the reversibility of the deprotonated 1 by HCl in both solution and the solid state (TLC paper test strips) was successful. In general, probe 1 is a promising CN- indicator in terms of its ease-of-use, selectivity, sensitivity, rapid response (<1 s), reversibility and test kit application. In the experiment, the researchers used many compounds, for example, 2,6-Diaminopyridine(cas: 141-86-6Related Products of 141-86-6)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Related Products of 141-86-6
