Highly selective and sensitive fluorescent sensing of oxalate in water.
Effective fluorescent sensing of oxalate in water is significant but still remains a challenge. By using indicator-displacement assays, a readily available macrocyclic copper(II) complex was found to show a sensitive off-on fluorescent sensing for oxalate with high selectivity and high binding affinity (>10(7) M(-1)) in water at neutral pH.
