The design and synthesis of six nickel charge transfer (CT) complexes are described herein. The six nickel CT complexes have a nickel center, two organic ligands coordinated with the nickel center to form a dianionic square planar supramolecule and an organic counter-cation as represented by Figure US09711738-20170718-C00001. The ligands and counter-cations are selected to optimize properties, such as molecular alignment, film morphology, and molecular packaging. Described herein, the ligands can be 2,3-pyrazinedithiol (L1), 1,2-benzenedithol (L2) or 2,3-quinoxalinedithol (L3) and the counter-cations can be diquat (2,2′-ebpy) or methyl viologen (4,4′-mbpy). The six nickel CT complexes can also be utilized semiconductor devices, such as thin film transistors or inverters. Processes are also provided for the fabrication of semiconductors devices. The processes can include fabricating a substrate with a bilayer octadecylphosphonic acid (ODPA)/Al2O3 dielectric and applying one of the six nickel charge transfer (CT) complexes to the substrate.
