The synthesis and photophysical evaluations of two new fluorescent photoinduced electron-transfer (PET) anion sensors, 1 and 2, is described. These are based on 4-amino-1,8-naphthalimide fluorophores and diarylthiourea anion receptors, connected via a methylene spacer to the imide. The sensing of acetate, phosphate, and fluoride, on all occasions, gave rise to quenching in the fluorescence of 1 and 2, similar to that seen for the structural isomer 3. These results demonstrate that bidirectional PET sensing occurs in such naphthalimide-based anion sensors.
描述了两种新型荧光光致电子转移（PET）阴离子传感器1和2的合成及光物理评估。它们基于4-氨基-1,8-萘二甲酰亚胺荧光团和二芳基硫脲阴离子受体，通过亚甲基间隔基与酰亚胺相连。在所有情况下，对乙酸根、磷酸根和氟离子的传感都会导致1和2的荧光猝灭，这与结构异构体3的情况类似。这些结果表明，在这种基于萘二甲酰亚胺的阴离子传感器中发生了双向PET传感。
