摘要：

A class of new fluorescence probe alpha-p-trifluoroacetamidophenyl-4-alkoxycinnamonitrile for detection of cyanide anion was synthesized by the trifluoroacetylation of the fluorophore alpha-p-aminophenyl-4-alkoxycinnamonitrile. It was found that the probe could selectively detect cyanide anions, even in the presence of hydrogen sulfite and dicarbonate anions which were reported to easily interfere with the detection. The concentration of the cyanide anions that could be detected was as low as 1.0 mu M. (C) 2013 Elsevier B.V. All rights reserved.
