A novel fluoride ion-triggered dual fluorescence molecular switch based on naphthalimides winged zinc porphyrin (1) was designed and prepared. The fluorescence of the zinc porphyrin unit could be regulated "ON-OFF" on the excitation of 365 nm and "OFF-ON" on the excitation of 504 nm, respectively, in the presence of fluoride ion. The obvious color changes induced by the intermolecular proton transfer on N-H fragments are clearly visible to the naked eye.
设计并制备了一种基于萘二甲酰亚胺修饰锌卟啉的新型氟离子触发双荧光分子开关(1)。在氟离子存在下,锌卟啉单元的荧光在365nm激发时可分别实现“开-关”调节,在504nm激发时实现“关-开”调节。由N-H片段上分子间质子转移引起的明显颜色变化肉眼清晰可见。
