A new ferrocene–anthracene dyad bearing amide and triazolium donors for dual-signaling sensing to anions

A new ferrocene–anthracene dyad anion receptor 1 bearing amide and 1,2,3-triazolium donor groups has been designed and synthesized. In CH3CN solvent, 1 shows a dual-signaling sensing toward H 2 PO 4 - over other anions, with its fluorescence a large enhancement, and electrochemical potential a negative shift.
