Two novel ferrocene-containing macrocyclic triazoles (L1 and L2) and their acyclic analogs (L3 and L4) were easily prepared by “click” reaction. The anions binding abilities of L1–L4 were evaluated by cyclic voltammetry and differential pulse voltammetry methods. The results revealed that the receptors L1–L4 have exclusive electrochemical sensing of H2PO4−, with the shift in redox potentials of L1–L4...
A new naphthalene-containing macrocyclic triazole (1) and its acyclic compared compound (2) have been synthesized and characterized. In acetonitrile and acetonitrile aqueous solutions, 1 and 2 showed good fluorescence sensing ability to Hg2+ over other metal ions, with 1 exhibiting better sensitivity and selectivity than 2 owing to its macrocyclic effect. 1H NMR titrations and DFT calculation results...
