基于萘酰亚胺的高选择性的比色和比率荧光探针的氟离子显示单光子和双光子比率变化。在与F-（TBA（+）和Na+盐）阴离子在CH 3CN以及缓冲水溶液中反应后，探针1显示出从无色到翠绿色的显著颜色变化和显著的比率荧光增强信号。这些性能在机械上归因于氟化物触发的Si-O键断裂，导致产生绿色荧光的4-氨基-1，8-萘酰亚胺。
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 CH3CN 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.
