    Facile Synthesis of 3-Alkoxy-4-cyanothiophenes As New Building Blocks for Donor−Acceptor Conjugated Systems
    摘要:
    3-Alkoxy-4-cyanothiophenes are efficiently synthesized in two steps from the readily available 4-cyano-3-oxotetrahydrothiophene. Regioisomers of bithiophene derivatives are easily synthesized by playing on the strong electronic dissymmetry of the thiophene ring induced by the alkoxy and cyano groups.

  • Clean and Efficient Iodination of Thiophene Derivatives

    Abstract Iodination of thiophene derivatives is realized using a simple, fast, and efficient methodology. Iodination of thiophene and 2- or 3-substituted or 3,4-disubstituted thiophenes with N-iodosuccinimide (NIS) activated with 4-toluenesulfonic acid in ethanol gives pure iodinated products that require no further purification. Iodination of thiophene derivatives is realized using a simple, fast

    A weak electron-donating building block, copolymers thereof and their preparation methods as well as their applications. The weak electron-donating building block provided by the present invention is of Formula I. In the present invention, incorporating strong electron-withdrawing substituents into the electron-rich 3, 3' -dialkyoxy-2, 2' -bithiophene leads to new monomers with weaker electron donating abilities and hence lower-lying HOMOs.
