Abstract
A method for forming a conjugated polymer which is doped by a dopant includes the steps of (a) adding a doping agent comprising a dopant moiety to a solution containing the conjugated polymer or a precursor thereof and, optionally, a second polymer, the dopant moiety being capable of bonding to the conjugated polymer, precursor thereof or the second polymer; (b) allowing the dopant moiety to bond to the conjugated polymer, precursor thereof or the second polymer to perform doping of the conjugated polymer, wherein the amount of doping agent added in step (a) is less than the amount required to form a fully doped conjugated polymer.
Claims35
A method for partial doping of a host conjugated polymer, comprising:
- blending a host conjugated polymer or a precursor thereof with a second polymer to form a polymer blend, the second polymer being substantially-miscible with the first polymer and derivatized with a small fraction of dopant groups or precursors thereof, and the small fraction being less than the amount required to fully dope the host conjugated polymer.
A method for partial doping of a host conjugated polymer in solution, comprising:
- incorporating a small mole fraction of a monomer into a host conjugated polymer to form a copolymer, the monomer being derivatized with a dopant group or precursor thereof, and the small mole fraction being less than the amount required to fully dope the host conjugated polymer.
