Abstract: 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 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.

Abstract: The design and fabrication of ultrathin poly-3-hexyl thiophene (P3HT) film based amine sensors are described herein. Ultrathin P3HT monolayer films can be built on a patterned flexible n-octadecylphosphonic acid (ODPA)/Al2O3/PET substrate, forming a flexible polymer thin film transistor according to a solution process. The mechanism of the sensor is based on the interaction of amine molecules with the surface of the P3HT monolayer. The interaction of amine molecules with the surface of the P3HT monolayer can affect the current density of the PTFT, and the change in current density can indicate the presence of amine molecules in the surroundings. The amine sensors described herein can easily detect amine molecules in a parts per billion (ppb) range. The amine sensors can be utilized, for example, as disposable sensors within food packaging to ensure the safety of the packaged food.
