ABSTRACT:
Thienothiophene monomers having an SF5group and conducting oligomers and polymers formed by the polymerization of such monomers and their use as hole injection materials, charge transport materials, or as semiconductors. The compound may be of the formula:where X and X′ are independently H, halogen atoms (e.g., F, Cl, Br, and I), MgCl, MgBr, Mgl, Sn(R′)3, where R′ comprises C1-6alkyl or —OC1-6alkyl, boronic acid, boronic ester, —CH═CHR″ (where R″ comprises H or C1-6alkyl), —OC1-6alkyl, —COOC1-6alkyl, —S—COR′″ and —COR′″ (where R′″ comprises H or C1-6alkyl), —C≡CH, or polymerizable aromatic rings (such as phenyl, naphthalene, pyrrole, dithiophene, thienothiophene, thiophene and so forth).
