Oligothiophenes. Part 4: Formation and characterization of stable radicals from novel bis- and tris-bithiophene methanes

Article abstract of DOI:10.1016/j.tetlet.2006.11.028

Two star-shaped structures of the bis- and tris-thiophene methane types have been synthesized in a facile two-step synthesis. The resulting bis- and tris-thiophene methanes readily react with oxygen both as solids and in solution to yield stable radicals.
