A terbium complex with long luminescence lifetime for the selective time-gated detection of potassium is presented. The complex demonstrates high sensitivity with a 25-fold increase in time-gated luminescence intensity between 0 and 15 mM potassium. The high selectivity of the complex for potassium over other physiological cations, and especially sodium (93 fold), is likely due to a favorable cation-pi
介绍了一种具有长发光寿命的铽配合物,用于钾的选择性时间门控检测。该复合物显示出高灵敏度,在 0 和 15 mM 钾之间的时间门控发光强度增加了 25 倍。复合物对钾的高选择性超过其他生理阳离子,尤其是钠(93 倍),可能是由于苯酚部分和钾离子之间有利的阳离子-π 相互作用。
