A facile and general two-step method towards 6,12-diaryl-5,11-dihydroindolo[3,2-b]carbazoles has been developed. Hydroiodic acid was an efficient catalyst for the condensation of indole and aromatic aldehydes, and iodine was used as an oxidation reagent to afford symmetrical 6,12-diaryl-5,11-dihydroindolo[3,2-b]carbazoles in moderate to good overall yields.
