Synthesis of novel carbazole derived substances using some organoboron compounds by palladium catalyzed and investigation of its semiconductor device characteristics

Carbazole compounds in particular represent one of the most intensely used and studied class of semiconducting materials. In this study, considering the information given in the literature the Ullman and Suzuki-Miyaura coupling reaction were carried out using carbazole, 1,4-dibromobenzene and pyrene-1-boronic acid. The synthesized carbazole derivatives are characterized by H-1 NMR and elemental analysis. The spectroscopic and thermal properties of the synthesized novel carbazole derivative 9-(4-(pyren-4-yl) phenyl)-9H-carbazole (Cz-py) were investigated. And also, the n-Si/p-Cz:py heterojunction diode was fabricated. The electrical properties of this diode were characterized by current-voltage (I-V) and capacitance-voltage (C-V) measurements.
