The development of copolymers based on ionic liquid vinyl monomers of the imidazole family combined with polymerizable chromophoric units is presented herein. For this end, ruthenium complexes bearing polymerizable vinyl groups or ω-end vinyl rr-poly(3-alkyl thiophene) were prepared and copolymerized with the ionic liquid monomers under free radical polymerization conditions, affording chromophore/polyelectrolyte
本文介绍了基于咪唑族离子液体乙烯基单体与可聚合发色单元结合的共聚物的开发。为此,制备带有可聚合乙烯基或ω-末端乙烯基rr-聚(3-烷基噻吩)的钌配合物,并在自由基聚合条件下使其与离子液体单体共聚,得到发色团/聚电解质的组合。此后,还合成均聚物离子液体以选择用于共聚物的最佳条件。对所有单体和聚合物的光学性质进行了表征,并使用各种互补技术对其进行了结构表征。在基于二氧化钛和充当空穴传输半导体聚合物的区域规则的聚(3-己基噻吩)的准固态敏化太阳能电池中测试了选定的共聚物和均聚物。可以与空穴导体混溶并可以与空穴导体沉积的离子液体提供了一种功能,该功能在某些情况下可支持开路电压的增加,从而提高了电池效率。
