RESUMO

A novel fluorescence sensing 1,8-naphthalimide fluorophore is synthesized and investigated. The novel probe comprising two different binding moieties is capable to detect selectively Fe3+ over the other representative metal ions as well as a combination of biologically important cations such as Fe3+, Cu2+ and Hg2+ in the physiological range without an interfering effect of the pHs. Due to the remarkable fluorescence changes in the presence of Fe3+, Hg2+ and Cu2+ ions, INH and AND logic gates are executed and the system is able to act as a single output combinatorial logic circuit with three chemical inputs.
