A novel method for the synthesis of soluble oligo(3-ethyl-2,5-thiophene ethylene)s was developed based on a rapid iterative divergent/convergent strategy that utilizes 3-ethyl-2-(trimethylsilylethynyl)thiophene. The synthetic strategy involved the iterative divergent/convergent process that doubles the framework after each stage of iteration. Furthermore, the synthetic strategy was characterized by iodination, protodesylation and Pd/Cu-catalyzed cross coupling reactions.

The synthetic organic phase of a project targetted toward the construction of molecular scale electronic devices is presented. A synthetic process for orthogonally fused conjugated organic oligomers is described. The final systems will have a potentially conducting chain fused perpendicularly to a second potentially conducting chain via a sigma bonded network. One of the core segments synthesized is based on a spirobithiophene moiety with a central silicon atom. The second core is a 9,9'-spirofluorene system.
