Abstract: Partially and fully fluorinated alkyl substituted thienothiophene monomers (and polymers thereof) wherein the monomers are represented by the formula: wherein R is a partially or fully fluorinated primary, secondary or tertiary alkyl having from 1 to 8 carbon atoms; and X and X? are independently selected from the group consisting of H, F, Cl, Br, I, MgCl, —COR?, —C?CH, and a polymerizable cyclic pi-conjugated carbon-ring structure optionally comprising S, N or O heteroatoms; wherein R? is a primary, secondary or tertiary alkyl having from 1 to 6 carbon atoms, and R? is H or a primary, secondary or tertiary alkyl having from 1 to 6 carbon atoms.

Abstract: Thienothiophene monomers having an SF5 group 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 1), MgCl, MgBr, Mgl, Sn(R?)3, where R? comprises C1-6 alkyl or —OC16 alkyl, boronic acid, boronic ester, -CH=CHR? (where R? comprises H or C1-6 alkyl), —OC1-6 alkyl, —COOC1-6 alkyl, —S—COR?? and —COR ? (where R ? comprises H or c1-6 alkyl), —C?CH, or polymerizable aromatic rings (such as phenyl, naphthalene, pyrrole, dithiophene, thienothiophene, thiophene and so forth).

Abstract: Thienothiophenes compositions comprising a C3-8 secondary or tertiary alkyl group are disclosed. The thienothiophenes may berepresented by the formula: where R is C3-8 secondary or tertiary alkyl, e.g., isopropyl, tert-butyl, tert-pentyl, isopentyl, and 2-ethylhexyl, X and X? are independently selected from the group consisting of H, halogen atoms (e.g., F, Cl, Br, and I), MgCl, MgBr, Mgl, Sn(R?)3, (where R? is C1-6 alkyl or —OC1-6 alkyl), boronic acid, boronic ester, —CH?CHR? (where R? is H or C1-6 alkyl), —OC1-6 alkyl, —COOC1-6 alkyl, —S—COR??, —COR?? (where R?? is H or C1-6 alkyl), —C?CH, and polymerizable aromatic rings such as phenyl, naphthalene, pyrrole, dithiophene, thienothiophene, thiophene and so forth.
