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.
