A molecular half-subtractor with Zn2+ and UV-light as inputs.
The salen-type Schiff base (2,2'-bis(2-hydroxybenzylideneamino)-1,1'-binaphthyl (BHB)) has been synthesized and characterized. Exhibiting absorption and fluorescence changes in the presence of Zn(2+) in chloroform and ethanol mixed solution, BHB could be used as a fluorescent chemosensor for the detection of Zn(2+). Furthermore, by monitoring the fluorescence and absorbance as output signals, BHB can function as a combinatorial logic circuit for a molecular half-subtractor with Zn(2+) and UV irradiation as input variables.
