A process includes providing furan-2,5-dicarboxylic dimethyl ester (FDME), reacting the FDME with a Grignard reagent to form a bis-alkylketone furan having R groups selected from the group consisting of a C.sub.1-C.sub.20 linear alkyl chain, a C.sub.2-C.sub.24 branched alkyl chain, and a hydrogen atom. An additional process includes mixing a 3,4-dibrominated bis-alkylketone furan with potassium carbonate, and adding ethyl-mercaptoacetate to the mixture. This process also includes stirring the mixture to form a bis-alkyl-DTF diester fused ring structure, which is then brominated to form a dibromo-DTF compound.

A composition for forming an electroactive coating includes an acid as a polymerization catalyst, at least one functional component, and at least one compound of formula (1) as a monomer:
