Abstract
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.
摘要
有效荧光检测水中草酸盐具有重要意义，但仍然是一个挑战。通过使用指示剂置换分析，发现一种易得的大环铜(II)配合物在中性 pH 水中对草酸盐具有高选择性和高结合亲和力（>10(7) M(-1))的灵敏的关闭-开启荧光检测。
