A naphthalimide-based highly selective colorimetric and ratiometric fluorescent probe for the fluoride ion displayed both one- and two-photon ratiometric changes. Upon reaction with the F(-) (TBA(+) and Na(+) salts) anion in CH(3)CN as well as in aqueous buffer solution, probe 1 shows dramatic color changes from colorless to jade-green and remarkable ratiometric fluorescence enhancements signals. These properties are mechanistically ascribed to a fluoride-triggered Si-O bond cleavage that resulted in a green fluorescent 4-amino-1,8-naphthalimide.
一种基于萘酰亚胺的高选择性比色和比率荧光探针，可用于氟离子。该探针在 CH(3)CN 以及水缓冲溶液中与 F(-)（TBA(+) 和 Na(+)盐）阴离子反应时，表现出一光子和两光子比率变化的显著比色和比率荧光增强信号。这些性质可以用氟化物触发的 Si-O 键断裂来解释，导致形成绿色荧光 4-氨基-1,8-萘酰亚胺。
