A redox-activated fluorescence switch based on a ferrocene-fluorophore-boronic ester conjugate

摘要

A novel electrochemically and fluorescence active boronic ester sensor molecule has been developed containing ferrocene and naphthalimide as the redox and fluorophore units. The combinations of iron (Fe3+) ions, sodium L-ascorbate, and fluoride (F-) ions can be used to produce a molecular system displaying INHIBIT logic, due to indirect fluorescence quenching.
