Abstract

A new naphthalimide derivative 1 is reported as an anion-activated CO2 chemosensor. Among the various anions, chemosensor 1 displayed selective colorimetric and fluorescence changes with F- and CN-. Hydrogen bonding interactions between amine groups and anions can be attributed to these changes. The exposure of CO2 revived the original color and fluorescence, so that distinct "On-Off-On" fluorescence emission changes were observed, for this anion-activated CO2 sensing mechanism.
