Studies On Synthesis, Characterization And Properties Of Ferrocene And Anthraquinone Based Multisite Recognition Receptors

In view of the redox-active receptors being great important to both theoretical field of supramolecular chemistry and practical areas of ion transport and molecular switches, an investigation on design, synthesis, and supramolecular properties of ferrocene and anthraquinone based multisite recognition receptors was systematically carried out. The main results are as follows:A total of 14 new ferrocene or/and anthraquinone derivatives were successfully synthesized. Their structures were fully characterized by elemental analysis, IR, ¹H NMR, ¹³C NMR and MS.In the first part, the recent research progress of ferrocene based redox-active receptors, including molecular design, chemical synthesis as well as their supramolecular electrochemical recognition and sensing properties, was briefly summarized.In the second part, two new ferrocene based acyclic multisite receptors containing triazole linkers were synthesized, and their electrochemical sensing properties were investigated via cyclic voltammetry.In the third part, two novel triferrocene polyether receptors containing both triazole and amide linkers were synthesized via CuAAC reaction. It was found that they have a high selectivity for sensing of H₂PO₄^– by the cyclic voltammetry and fluorescence titration. In addition, they also show an efficient fluorescence in the presence of Cu²⁺ ion.In the last part, two novel anthraquinone bridged multisite receptors containing triazole-linked ferrocene moieties were successfully synthesized.
