A new artificial receptor 1 was synthesized for the detection of Fe(3+) and Mg(2+) in solution as a colorimetric and fluorescent sensor, respectively. The sensor exhibited highly selective and sensitive recognition towards Fe(3+) in CH(3)CN via color change from colorless to brown. Also it showed a significant fluorescence enhancement (70-fold) towards Mg(2+) in the mixture of solution CH(3)CN/H(2)O (8:2, v/v). The selectivity of either Fe(3+) or Mg(2+) was not interfered by the presence of other metal ions such as Cr(3+), Mn(2+), Co(3+), Ni(2+), Cu(2+), Ag(+), Cd(2+), Pb(2+), Ca(2+) and K(+) ions.
一种新型的人工受体 1 被合成出来，用于分别作为比色和荧光传感器检测溶液中的 Fe(3+)和 Mg(2+)。该传感器通过从无色到棕色的颜色变化，对 CH(3)CN 中的 Fe(3+)表现出高度选择性和灵敏的识别。同时，它对混合溶液 CH(3)CN/H(2)O（8:2，v/v）中的 Mg(2+)表现出显著的荧光增强（70 倍）。Fe(3+)或 Mg(2+)的选择性不受其他金属离子如 Cr(3+)、Mn(2+)、Co(3+)、Ni(2+)、Cu(2+)、Ag(+)、Cd(2+)、Pb(2+)、Ca(2+)和 K(+)离子的存在干扰。
