  Synthesis and Electronic Properties of D–A–D Triads Based on 3-Alkoxy-4-cyanothiophene and Benzothienothiophene Blocks

  摘要：

  3-Alkoxy-4-cyanothiophene units are used as building block for the synthesis of conjugated donor acceptor donor (D-A-D) triads. The donor part consists of benzothienothiophene end groups associated with the alkoxy groups of the 3-alkoxy-4-cyanothiophene, while the central acceptor part is formed by combining the electron-withdrawing cyano group with thiophene or benzothiadiazole units.

  日期：——

  A symmetrical donor–acceptor–donor D–A–D system built by connecting two dithienopyrrole donor blocks to a central electron acceptor obtained by dimerization of 3-alkoxy-4-cyano-thiophene has been synthesized and characterized. The compound combines a high photoluminescence efficiency with a broad absorption spectrum in the solid state and a band gap of 1.70 eV. A preliminary evaluation of the potentialities of this type of compound as donor material in bulk heterojunction solar cells using PC61BM as electron acceptor is presented.
