A series of 3,6-dialkoxythieno[3,2-b]thiophenes have been synthesized through three synthetic pathways. Symmetrical derivatives have been obtained from 3,6-dibromothieno[3,2-b]thiophene or by trans-etherification of 3,6-dimethoxythieno[3,2-b]thiophene while unsymmetrical derivatives have been easily prepared from the readily accessible dimethyl 3-hydroxythiophene-2,5-dicarboxylate. These compounds have been used as precursors for electropolymerisation and a first characterisation of the electronic properties of the resulting polymers is presented.
通过三条合成路径,已成功合成了3,6-二烷氧基噻吩并[3,2-b]噻吩系列化合物。对称衍生物由3,6-二溴噻吩并[3,2-b]噻吩或通过3,6-二甲氧基噻吩并[3,2-b]噻吩的反式醚化获得,而异构衍生物则通过易于获得的二甲基3-羟基噻吩-2,5-二羧酸酯轻松制备。这些化合物作为电化学聚合的前体,其所得聚合物的电子特性首次得到了表征。
