在6-位引入单-和二-吡啶甲基氨基官能团的酞衍生物已被制备为新型的荧光离子载体，并研究了它们对金属阳离子的荧光响应。这些苯酞不仅在水介质中表现出有效的荧光，而且在添加过渡金属阳离子，即Cu（2+）时显示荧光开关响应。6-氨基苯酞荧光团作为荧光探针的核心，但它很少被应用于化学传感器。据我们所知，这些改性苯酞是第一个6-氨基苯酞衍生的金属阳离子，即Cu（2+）的荧光探针。
Phthalide derivatives incorporating mono- and di-picolylamino functionalities at the 6-position have been prepared as novel fluoroionophores and their fluorescence responses to metal cations have been investigated. These phthalides not only exhibited efficient fluorescence in an aqueous medium but also displayed fluorescence on-off response upon addition of transition-metal cations, namely Cu(2+). The 6-aminophthalide fluorophore served as the core of the fluorescent probes although it has rarely been applied to a chemosensor. To the best of our knowledge, these modified phthalides are the first 6-aminophthalide-derived fluorometric probes for metal cations, namely Cu(2+).
