Synthesis of 3,4-alkoxythieno[2,3-b]thiophene derivatives. The first block copolymer associating the 3,4-ethylenedioxythieno[2,3-b]thiophene (EDOThT) unit with 3,4-ethylenedioxythiophene (EDOT) moieties

The synthesis of 3,4-alkoxythieno[2,3-b]thiophene derivatives has been developed from the readily accessible dimethyl or diethyl 3,4-dihydroxythieno[2,3-b]thiophenedicarboxylates. The yields for the dialkoxy derivatives were strongly dependent both on the base and the alkylating agent used for the nucleophilic substitutions. A trimer associating the new 3,4-ethylenedioxy-thieno[2,3-b]thiophene unit with 3,4-ethylenedioxythiophene moieties has been synthesized and electropolymerized.
我们从容易获得的 3,4-二羟基噻吩并[2,3-b]噻吩二羧酸二甲酯或二乙酯中开发出了 3,4-烷氧基噻吩并[2,3-b]噻吩衍生物的合成方法。二烷氧基衍生物的产率在很大程度上取决于碱和用于亲核取代的烷基化剂。新的 3,4-亚乙二氧基噻吩并[2,3-b]噻吩单元与 3,4-亚乙二氧基噻吩分子的三聚体已被合成和电聚合。
