A 1,8-naphthalimide group modified magnetic silica nanoparticles INHIBIT logic gate with H+ and F− as inputs

In this work, molecular logic element modified multifunctional silica nanoparticles having high magnetization have been successfully prepared. These multifunctional nanoparticles were characterized by Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), Elementary analysis, X-ray powder diffraction (XRD) and Vibrating sample magnetometer (VSM). The characterization datum indicated that the organic ligand was successfully grafted on the surface of the magnetic silica nanoparticles . The fluorescent changes of the hybrid material upon the addition of cations (H + , F − and their mixture) is utilized as an INHIBIT logic gate at the molecular level, using the fluorescence intensity signal as output.
