    摘要: Solid, or highly viscous, organic electrolytes consisting of alkylimidazolium cation with alkyl, PEGylated and fluorinated side chains of different molecular weights were synthesized and characterized (cf. chemical structures in Schemes 1 and 2). The PEGylated/fluorinated imidazolium iodide is a solid organic electrolyte that has a conductivity of about 2×10−5 S/cm at 30° C. The ionic conductivity could be significantly increased (1.11×10−4 S/cm at 30° C. and S/cm at 2.88×10−3 at 90° C.) by blending the PEGylated/fluorinated imidazolium iodide with another solid electrolyte, 1-ethyl-3-methylimidazolium iodide (EtMImI). The PEGylated imidazolium iodides synthesized in the present work have conductivities in the range 1.6×10−4 S/cm to 2×10−4 S/cm at 30° C. and viscosities in the range 620 cP to 720 cP at 30° C. The iodide counter ion in the present electrolytes supplies the anion for the I−/I3− redox mediators for DSSCs. Therefore, the organic electrolytes of the present invention can be used even without the addition of inorganic salts such as LiI or KI. We found that the addition of an organic solid electrolyte, EtMImI, resulted in an increase in the ionic conductivity of the PEGylated/fluorinated imidazolium iodides, whereas the addition of the inorganic LiI led to a decrease in ionic conductivity. All the electrolytes are thermally stable until high temperatures (250° C. to 300° C.).

    摘要: The present invention relates conductive nanostructured copolymer materials, such as thin film. In particular, the nanostructured copolymer material comprises plurality of chains substantially parallel to each other, each conductive chain comprising a plurality of conductive polyacetylene polymer blocks positioned along the chain and a plurality of polar poly(vinyl alcohol) polymer blocks in between the polyacetylene polymer blocks to form a pattern of alternatively repeating polyacetylene polymer blocks and poly(vinyl alcohol) polymer blocks and a ratio of polyacetylene polymer to poly(vinyl alcohol) polymer to provide the nanostructured copolymer material with conductivity of at least 1 S/cm. In some aspects, the invention relates to photoelectric devices comprising a nanostructured copolymer material and capable to convert light to electrical current.
