• Cation-pi interaction
• Hg2+
• Density functional theory (DFT)

Two sulphur-containing 4-aminonaphthalimide derivatives were investigated as Hg2+ fluorescent chemosensors. In CH3CN, both sensors present a remarkable fluorescence enhancement to Cu2+ and Fe3+, but a selective fluorescence quenching to Hg2+ among the other metal ions. A cation-p interaction between Hg2+ and the naphthalimide moiety was proposed and confirmed by the density functional theory(DFT).
