The diindenocarbazole derivatives are synthesized by the reaction of 2,7-dibromo-9-hexylcarbazole with benzoyl chloride underFriedel-Craftsconditions, followed by Wolff-Kishner-Huang reduction to produce 3,6-dibenzyl-2,7-dibromo-9-hexylcarbazole, which was cyclized to form bis(indeno)-9-hexylcarbazole by palladium-catalyzed doubleintramoleculararylation. The diindeno-carbazole was further converted
