title: A pentaquinone based probe for relay recognition of F- and Cu2+ ions: sequential logic operations at the molecular level.
abstract: A pentaquinone based compound (2a) has been synthesized, which can selectively sense F(-) ions via fluorescence quenching, while the in situ generated deprotonated species of 2a can recognize Cu(2+) ions via a fluorescence enhancement. Derivative 2a can also behave as a sequential logic circuit with chemical inputs from F(-) and Cu(2+) ions.
