ABSTRACT:
Disclosed are polymers comprising 2-(7-benzothiazolyl-9,9-disubstituted fluorene) structural units of the formulawherein R1and R2are each independently an alkyl group, an aralkyl group, an aryl group, or an —Si(R)3group wherein R is an alkyl group; R3is selected from the group consisting of an electron-donating substituent and an electron-withdrawing substituent; x has the value of from zero up to the number of hydrogens available for substitution on the aromatic ring; Z and Q are each independently a group which is in conjugation with both the fluorene group and the benzothiazole group; and the parameters j and k each independently have the value of 0–2. Electroactive devices comprising said polymers, methods for preparing said polymers, and monomers for preparing said polymers are also disclosed.
