ABSTRACT:
Partially and fully fluorinated alkyl substituted thienothiophene monomers (and polymers thereof) wherein the monomers are represented by the formula:whereinR is a partially or fully fluorinated primary, secondary or tertiary alkyl having from 1 to 8 carbon atoms; andX 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;whereinR′ is a primary, secondary or tertiary alkyl having from 1 to 6 carbon atoms, andR″ is H or a primary, or tertiary alkyl having from 1 to 6 carbon atoms.
