合成了一种新的人工受体1，分别作为比色和荧光传感器检测溶液中的Fe3+和Mg2+。该传感器对CH3CN中的Fe3+具有高度的选择性和灵敏度，可以通过颜色由无色变为棕色来识别。在CH3CN/H2O （8:2, v/v）的混合物中，对Mg2+的荧光增强（70倍）显著。Cr3+、Mn2+、Co3+、Ni2+、Cu2+、Ag+、Cd2+、Pb2+、Ca2+和K+等金属离子的存在均不影响Fe3+和Mg2+的选择性。(C) 2012 Elsevier B.V.版权所有
A new artificial receptor 1 was synthesized for the detection of Fe3+ and Mg2+ in solution as a colorimetric and fluorescent sensor, respectively. The sensor exhibited highly selective and sensitive recognition towards Fe3+ in CH3CN via color change from colorless to brown. Also it showed a significant fluorescence enhancement (70-fold) towards Mg2+ in the mixture of solution CH3CN/H2O (8:2, v/v). The selectivity of either Fe3+ or Mg2+ was not interfered by the presence of other metal ions such as Cr3+, Mn2+, Co3+, Ni2+, Cu2+, Ag+, Cd2+, Pb2+, Ca2+ and K+ ions. (C) 2012 Elsevier B.V.
