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.
