Özet

© 2023 Wiley Periodicals LLC.Herein, aromatic polyimides (API) synthesis was carried out by polycondensation of the original diamine (new synthesis) and commercial dianhydride. The original diamine and API were characterized by different analysis techniques. In addition, experimental and quantum chemical calculations of the synthesized API were analyzed by density functional theory method. Quantum theory analysis of atoms in molecules was performed for a structural unit of the compound. Here, the proton transfer phenomenon was investigated. The main purpose of synthesizing API1 was diode application. Therefore, the Au/API-p-Si/Al diode was produced accomplishedly. When the electrical characterization of the obtained diode structure was made, electrical parameter values such as ideality factor (n) (between 1.9 and 3.8), barrier height (ΦB) (0.73–0.28 eV), and series resistance (Rs) (1270–40,187 kΩ) were calculated.
