In this paper, firstly, a new organic material 9 containing triphenylamine (TPA) unit as an electron donor and diaminomaleonitrile (DAMN) unit as an electron acceptor and thiophene scaffold as a π‐linker bridge was designed for diode applications according to D‐π‐A architecture. The organic material 9 was synthesized in four reaction steps with excellent yield (94 %), and fully characterized by 1H NMR, 13C NMR, FTIR, and HRMS spectra. The diode performance properties of the obtained organic material were examined in detail. Current‐voltage (I–V) and capacitance‐voltage (C–V) measurements of this diode were carried out. As a result of the analysis of these measurements, the effect of the organic material used as the interface material on the electrical properties of the diode was analyzed. A new organic material in TFA‐thiophene‐phenly‐DAMN hybrid structure with D‐π‐A architecture was for the first time designed and synthesized in four reaction steps in good yield (94 %). The obtained material was fully characterized by 1H NMR, 13C NMR, FTIR, and HRMS spectra. The diode performance properties of the obtained organic material were examined in detail. Current‐voltage (I–V) and capacitance‐voltage (C−V) measurements of this diode were carried out.
