互补半导体聚合物共混物（c-SPB）的概念最近被提出来实现有机电子器件的增强的溶液加工性和/或熔融加工能力。在以前的研究中，我们证明了矩阵聚合物的共轭断裂间隔的影响。在目前的工作中，我们探讨了基体聚合物的侧链对纯聚合物及其相应的c-SPBs的物理性质的影响，包括电性能和相变行为。合成并表征了六种含有五亚甲基共轭断裂间隔基（CBSs）和各种侧链（包括支链烷基、三甘醇（TEG）和正戊烷封端的侧链）的二酮基吡咯并吡咯（DPP）聚合物。紫外-可见光谱表明，侧链对固态下的分子间相互作用有明显的影响。此外，侧链对聚合物的热行为也有重要影响。聚合物作为...
The concept of complementary semiconducting polymer blends (c-SPBs) has been recently proposed to achieve enhanced solution processability and/or melt-processing capability for organic electronics. In the previous study, we demonstrated the impact of conjugation-break spacers of matrix polymers. In the current work, we explore the influence of the side chains of the matrix polymer on the physical properties of the pure polymers and their corresponding c-SPBs, including electrical properties and phase transition behaviors. Six diketopyrrolopyrrole (DPP)-based polymers with pentamethylene conjugation-break spacers (CBSs) and various side chains, including branched-alkyl, triethylene glycol (TEG), and siloxane-terminated side chains, were synthesized and characterized. The UV–vis spectra show that the side chains have a noticeable impact on the intermolecular interactions in the solid states. In addition, side chains also have a significant influence on the thermal behaviors of the polymers. Polymers with as...
