A mixed metal inorganic complex which resembles redox sensitivity will be presented. Molecular switches experience a reversible physical change due to various external stimuli such as: high energy radiation, electrical current, heat, magnetic fields, and ultraviolet or visible light. We have synthesized a series of Group IVB and VB complexed to VIIIB metals that undergo intermolecular electron transfer upon high energy exposure resulting in a state change. In addition, we have found that substituting a Group IVB with selected Lanthanide metals results in fluorescently active compounds. We will present how the structure dictates the function of these complexes as sensors by analysis using nuclear magnetic resonance spectroscopy (NMR), Fourier-transform infrared spectroscopy (FT-IR), Raman spectroscopy, ultraviolet and visible spectroscopy (UV-Vis), fluorescence spectroscopy, energy dispersive x-ray spectroscopy, and cyclic voltammetry.
