A technique is described for the preparation of polymers according to a new process, in which the starting compound of formula (I) is polymerized in the presence of a base, in an organic solvent. No end chain controlling agents are required during the polymerisation to obtain soluble precursor polymers. The precursor polymer such obtained comprises structural units of the formula (II). In a next step, the precursor polymer (II) is subjected to a conversion reaction towards a soluble or insoluble conjugated polymer by thermal treatment. The arylene or heteroarylene polymer comprises structural units of the formula III. In this new process the dithiocarbamate group acts as a leaving group and permits the formation of a precursor polymer of structural formula (II), which has an average molecular weight from 5000 to 1000000 Dalton and is soluble in common organic solvents. The precursor polymer with structural units of formula (II) is thermally converted to the conjugated polymer with structural formula (III).
本发明描述了一种按照新工艺制备聚合物的技术,其中式(I)的起始化合物在碱存在下于有机溶剂中聚合。聚合过程中无需使用端链控制剂,即可获得可溶的前体聚合物。这样得到的前体聚合物由式(II)的结构单元组成。下一步,前体聚合物 (II) 将通过热处理进行转化反应,生成可溶或不溶的共轭聚合物。该芳基或杂芳基聚合物由式 III 的结构单元组成。在这种新工艺中,二硫代氨基甲酸基团作为离去基团,可形成结构式(II)的前体聚合物,其平均分子量为 5000 至 1000000 道尔顿,可溶于普通有机溶剂。结构单元为式(II)的前体聚合物经热反应转化为结构式(III)的共轭聚合物。
