Palladium-catalyzed Suzuki Miyaura cross coupling reactions (SM Coupling) are made using organoboronic acid and halides. 9-(4-anthracene-9-yl-phenyl)-9H-carbazole (III) was synthesized by using Ullman and Suzuki coupling reactions. Structural analysis of the 9-(4-anthracene-9-yl-phenyl)-9H-carbazole (III) compounds obtained by this method has been elucidated by 1H-NMR. This compound was dissolved by chloroform and the borosilicate glass was coated with drop casting method. Transmittance measurement of this film was taken and optical band value was determined. The heterojunction structure (n-Si/III) was fabricated by using the obtained compounds. The electrical properties of the fabricated photodiode were investigated.
