A Multianalyte Chemosensor on a Single Molecule: Promising Structure for an Integrated Logic Gate

A novel fluorescent probe that possess both BODIPY and Rhodamine moieties has been designed for the selective detection of Hg2+ and Ba2+ ions on the controlling by a logic gate. The characteristic fluorescence of the Ba2+-selective OFF−ON and the Hg2+-selective fluorescence bathochromic shift can be observed, and the concept has been used to construct a combinational logic circuit at the molecular level. These results will be useful for further molecular design to mimic the function of the complex logic gates on controlling.
