Abstract:

Described is the synthesis of oligo2-ethylphenyl-ethynylenes and oligo2-3ethylheptylphenyl-ethynylenes via an iterative divergent convergent approach. Synthesized were the monomer, dimer, tetramer, and octamer of the ethyl derivative and the monomer, dimer, tetramer, octamer, and 16-mer of the ethylheptyl derivative. The 16-mer is 128 A long. At each stage in the iteration, the length of the framework doubles. Only three sets of reaction conditions are needed for the entire iterative synthetic sequence an iodination, a protodesilation, and a PdCu-catalyzed cross coupling. The oligomers were characterized spectroscopically and by mass spectrometry.
