dc.description.abstract | The naphthalene urea fluorescent receptor 1 immobilized mesoporous silica (EMS) and the fluorescent receptor 1 immobilized silica particles (FSP) were prepared via sol-gel reaction. The sensing ability of FMS and FSP was studied by addition of the anions F-, Cl, Br, I- and HSO4- to water suspensions of the assayed solid. Of all the anions tested, addition of fluoride ion to a suspension of FMS resulted in the largest decrease in the fluorescence intensity of naphthalene of FMS. Thus, fluoride ions bind with four urea N-H protons of receptor 1 onto FMS. On the other hand, addition of Cl-, I-, Br- and HSO4- did not reduce the fluorescence of FMS. In case of FSP, the sensitivity for fluoride ion was 8 times lower than that of EMS due to immobilization of smaller amounts of receptor 1 in silica particles. The result implies that mesoporous silica with its large surface area is useful as a supporting material. (C) 2008 Elsevier Inc. All rights reserved. | - |
