Electrochemical bromide sensing with a halogen bonding [2]rotaxane
The selective electrochemical sensing of heavy halides such as bromide over more charge‐dense counterparts like chloride using mechanically‐interlocked structures remains a formidable challenge. Using the active‐metal templation methodology, the first redox‐active ferrocene‐appended rotaxane contain...

| description | The selective electrochemical sensing of heavy halides such as bromide over more charge‐dense counterparts like chloride using mechanically‐interlocked structures remains a formidable challenge. Using the active‐metal templation methodology, the first redox‐active ferrocene‐appended rotaxane containing an all‐halogen bonding anion binding cavity was synthesised. 1H NMR binding studies in aqueous‐organic solvent media demonstrated a marked recognition bias for heavy halides, facilitating the selective redox sensing of bromide over chloride to be demonstrated for the very first time with an interlocked host molecule. |
