Patent ID: 7173140

Claim:
A process for polymerizing indolocarbazole moieties comprising: reacting a reaction mixture comprised of one or more optionally substituted indolocarbazoles, a reaction medium, and a coupling agent at a reaction temperature to form a polymer comprising a plurality of optionally substituted indolocarbazole moieties which are the same or different from each other, wherein the coupling agent is an oxidizing agent selected from the group consisting of FeCl 3 , FeBr 3 , Fe 2 (SO 4 ) 3 , RuCl 3 , MoCl 5 , Na 2 S 2 O 8 , K 2 S 2 O 8 , K 2 Cr 2 O 7 , KMnO 4 , KBrO 3 , and KClO 3 , or a mixture thereof.
