Versuchsvorschrift

1.07 g of the indole-5-carboxylic acid trimer synthesized in Example 12 was suspended in 30 ml of 10% aqueous sulfuric acid-methanol solution, and the suspension was agitated for 2 hours at the temperature of 25° C. The suspension was suction-filtered with a perforated funnel, washed with methanol and dried to obtain 1.00 g of 6,11-dihydro-5H-diindolo [2,3-a:2′,3′-c] carbazole-2,9,14-tricarboxylic acid (indole-5-carboxylic acid trimer) with a light green color. 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 0.55 S/cm. The result of elemental analysis was: <C9.00H4.90N1.09O1.98Cl0.03(SO4)0.12>3.
