Puzzlingly logical: The characteristic fluorescence of Hg2+-selective OFF-ON and Cu2+-selective ON-OFF operations can be monitored and controlled reversibly by the sequence and ratio of Hg2+ and Cu2+ inputs. These inputs have been used to construct a molecular keyboard that is capable of crossword puzzles and logic memory (see picture).
