We present the synthesis of novel conjugated polymer-porphyrin complexes for use in organic electronics. Linear and star-shaped platinated porphyrins were attached to regioregular poly(3-hexylthiophene-2,5-diyl) (P3HT) arms to investigate whether porphyrin stacking and increased dimensionality can be used to control polymer morphology. The novel materials display similar optical properties to P3HT, but give higher mobilities when used in organic field-effect transistors. Atomic force microscopy measurements show that incorporation of only a small amount of porphyrin into the conjugated polymer backbone leads to increased aggregation. These materials demonstrate that polymer morphology and performance can be tuned and enhanced effectively through the use of conjugatively linked porphyrins.
我们展示了用于有机电子学的新型共轭聚合物 - 卟啉复合物的合成。将线性和星形铂化卟啉连接到区域规整的聚(3 - 己基噻吩 - 2,5 - 二基)(P3HT)臂上,以研究卟啉堆积和增加的维度是否可用于控制聚合物形态。这些新型材料表现出与P3HT相似的光学性质,但在有机场效应晶体管中使用时具有更高的迁移率。原子力显微镜测量表明,仅将少量卟啉掺入共轭聚合物主链中会导致聚集增加。这些材料表明,通过使用共轭连接的卟啉,可以有效地调节和增强聚合物的形态和性能。
