Reaction Steps

15 ml of acetonitrile was poured into a 200 ml three-neck flask, and 1.59 g of 6-acetylindole was dissolved therein. On the other hand, preparation of an oxidant solution was performed by dissolving 16.2 g of ferric chloride anhydrate and 5.4 g of water in 100 ml of acetonitrile and agitating the resultant mixture solution for 15 minutes. Then, the prepared 6-acetyl indole solution was dripped over 60 minutes into the oxidant solution, and the resultant mixture solution was agitated for 5 hours at the temperature of 30° C. Color of the reaction solution changed from yellow to blue-green with slight heat generation. pH of the reaction solution was less than 1. After the end of the reaction, the reaction liquid was suction-filtered with a perforated funnel, and the filtrate was washed with acetonitrile and then methanol, and was dried to obtain 1.11 g of 3,8,13-triacetyl-6,11-dihydro-5H-diindolo [2,3-a:2′,3′-c] carbazole (6-acetyl indole trimer) with a blue-green color (yield: 70%). The resultant trimer was pressure-molded with a tablet molding machine and the mold was cut into a piece with the diameter of 10 mm and thickness of 1 mm. A conductivity thereof was measured by the four terminal method and found to be 0.90 S/cm. The result of elemental analysis was: <C10.00H6.99N0.98O1.98Cl0.10>3.
