Fluorescence turn-on and turn-off mechanisms of a dual-selective chemosensor of Bi3+ and pH changes: Insights from a theoretical perspective
(Elsevier Ltd, 2021-02)
The N-hydroxy 1,8-naphthalimide (LH) is an optical dual-selective chemosensor toward Bi3+ ions as well as pH changes. In specific, this senor is selective to Bi3+ ions, which turn-on the fluorescence upon their interaction; ...
