  Visual and reversible detection of cyanide ions in protic solvents by a novel colorimetric receptor

  摘要：

  A novel colorimetric chemodosimeter for cyanide (CN-) and 1-allyl-4-[2-(4-hydroxyphenyfletheny1)]-quinolinium bromide (AHPEQB) was designed and synthesized by condensation and terminal N alkyl reaction. AHPEQB exhibited highly selective and sensitive recognition properties toward CN- over other competing anions in ethanol, a protic solvent, with a 1:1 binding stoichiometry and a detection limit of 1.7 Chi 10(-6) mol L-1. AHPEQB also displayed rapid colorimetric response that could be readily observed by the naked eye and good reversibility. The sensing mechanism of the proposed chemodosimeter was studied by UV-Vis, H-1 NMR titration, and comparison 1-ally1-4-[2-(4-acetoxyphenyfletheny1)]-quinolinium bromide (AAPEQB). The calorimetric chemodosimeter showed high accuracy in determining the concentration of CN- in real water samples. (C) 2014 Elsevier Ltd. All rights reserved.
