title: Spectral Switching of Naphthalimide-Coumarin Induced by F-.
abstract: A highly selective color sensor based on naphthalimide and coumarin was reported. Upon addition of F-, the solution color changed from pale yellow to deep blue. The sensor shows excellent selectivity against other common anions. The underlying mechanism for the color change is based on the deprotonation/protonation of the dye. Frontier molecular orbitals analysis gives further insight about the signaling mechanism.
