| 英文摘要 | A highly selective and sensitive fluorescent 'turn-on' and chromogenic chemodosimeter based on tetrahydro[5]helicene thioimide has been developed. The chemodosimeter showed not only 200-fold enhancement of the fluorescent intensity in aqueous acetonitrile, but also marked color change of the solution from maroon to yellow-green solution upon the addition of Hg2+ ion. The detection limit of the chemodosimeter for Hg2+ was estimated to be 5.0 x 10(-7) M. The response mechanism was resulted from the Hg2+-induced desulfurization of the thioimide to its imide precursor. (C) 2014 Elsevier B.V. All rights reserved. |
