Iterative Divergent/Convergent Approach to Linear Conjugated Oligomers by Successive Doubling of the Molecular Length: A Rapid Route to a 128Å‐Long Potential Molecular Wire

An iodination, a protodesilylation, and a Pd/Cu-catalyzed cross coupling are the three reactions needed to successively double the length of molecular units to form 1, a 128 Å long linear 16-mer, in a doubling sequence with only four iterations. Compound 1 could possibly serve as a molecular wire in molecular electronics studies.
