title: Fluoride triggered fluorescence "turn on" sensor for Zn2+ ions based on pentaquinone scaffold that works as a molecular keypad lock.
abstract: A pentaquinone based compound 3a has been synthesized which exhibits pronounced fluorescence enhancement in the presence of Zn(2+) ions under a F(-) triggered synergistic effect. Derivative 3a also behaves as a molecular keypad lock with sequential chemical inputs of Zn(2+) and F(-) ions.
