A multianalyte chemosensor on a single molecule: Promising structure for an integrated logic gate

(Figure Presented) A novel fluorescent probe that possess both BODIPY and Rhodamine moieties has been designed for the selective detection of Hg ²⁺ 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.
