A supramolecular host-guest complex stimulated by lithium cation and fluoride anion, functioning as reliable fluorescence "Off-On-Off" switching system has been developed. Nonfluorescent, receptor-bound fluorophore is exclusively displaced by second guest, fluoride anion to release the fluorophore that becomes highly fluorescent in guest concentration dependent way. Again, this process is completely
已开发出一种由锂阳离子和氟阴离子刺激的超分子主客体复合物,可用作可靠的荧光“关-开-关”切换系统。非荧光的、受体结合的荧光团被第二客体氟阴离子完全取代,以释放荧光团,该荧光团以客体浓度依赖的方式变得高度荧光。同样,这个过程在暴露于 Li + 时完全逆转。整个过程是基于荧光的逻辑系统的优秀模型。
