Abstract
A novel monomer design for the synthesis of PPE-type polymers containing conjugated segments of well-defined length connected by flexible linkers under Sonogashira reaction conditions is presented. The resulting polymers retain the photophysical properties of a fully conjugated PPE. The extent of incorporation of the flexible units along the backbone is governed by the comonomer feed ratio and can be varied in a statistically predictable fashion.
Claims11
A conjugated polymer, comprising a poly(p-phenylene-ethynylene) (PPE) having a flexible linker between a portion of phenylene units, comprising the structure:
- wherein R1 and R2 independently are substituents that provide solubility and/or a functionality for bonding or associating with a molecule, wherein X is a flexible unit of at least two atoms that do no conjugate with the adjacent phenylenes, and wherein x+y is 2 to 100,000 and x is 0.01y to 100y.
