摘要:
Compositions are provided comprising at least one conductive polymer and at least one non-polymeric fluorinated organic acid, salt or ester, wherein the conductive polymer is selected from a polythiophene, a polypyrrole, a polyaniline, and combinations thereof. Electronic devices and applications having at least one layer comprising such compositions are further provided.
摘要:
The present invention relates to compositions of matter that are useful as ionic liquids. The compositions of the invention are based on an N-substituted pyrrolidinone, said pyrrolidinone having a pendant ammonium cation that is separated from the pyrrolidone ring by a variable length alkyl spacer. The compositions comprise fluoroalkyl sulfonate anions.
