Embodiment 1
[0123] Embodiment 1: synthesis is represented by the compound of chemical formula 12
[0124] As an example of a compound for an organic photoelectric device in the present invention, a compound represented by Chemical Formula 12 was synthesized according to Reaction Scheme 1.
[0125]
[0126] Step 1: Synthesis of compound (A)
[0127] Mix 5 g (15.5 mmol) of 3-bromo-6-phenylcarbazole, 6.3 g (17.1 mmol) of 3-phenyl-6-carbazole boric acid pinacol ester in a 250 mL round bottom flask using a stirrer under nitrogen atmosphere And 100mL tetrahydrofuran mixed with 2M potassium carbonate aqueous solution. The mixture was heated to reflux for 12 hours under nitrogen flow. After the reaction was completed, hexane was added to the reactant. The solid generated therein was then filtered and dissolved in a mixed solution prepared by mixing toluene and tetrahydrofuran at a volume ratio of 50:50, to which activated carbon and anhydrous magnesium sulfate were added. Then stir the m...
