This study investigates a supramolecular approach to elucidate the interaction between an organic semiconducting molecule, specifically butyric acid-functionalized perylene diimide, and a block copolymer comprising poly-3-hexyl thiophene-b-polyethylene glycol. This interaction results in the formation of a precisely structured nanoarchitecture within the supramolecular block copolymer, driven by the ionic interplay between the block copolymer and small organic molecules. The optical properties of the synthesized supramolecular block copolymer were characterized by using ellipsometry. Additionally, further characterization employing atomic force microscopy, differential scanning calorimetry, and X-ray diffraction provided detailed insights into the crystallinity and morphology of the nanostructure. The characterization data showed that this approach significantly influenced the tuning of morphology, crystallinity, and optical and electronic properties of the resulting nanostructure. The demonstrated methodology holds considerable promise as a strategic tool for broadening the spectrum of attainable nanomorphologies in semiconducting polymers, particularly for applications in electronics or photovoltaics.
本研究探讨了一种超分子方法，以阐明有机半导体分子（具体为丁酸官能化的苝二酰亚胺）与包含聚-3-己基噻吩-b-聚乙二醇的嵌段共聚物之间的相互作用。这种相互作用在超分子嵌段共聚物中导致形成精确结构的纳米结构，这是由嵌段共聚物与小分子之间的离子相互作用驱动的。通过椭偏仪对合成的超分子嵌段共聚物的光学性质进行了表征。此外，采用原子力显微镜、差示扫描量热法和X射线衍射进行的进一步表征，提供了有关纳米结构的结晶度和形态的详细见解。表征数据表明，这种方法显著影响了所得纳米结构的形态、结晶度以及光学和电子性质的调控。所展示的方法作为一种战略工具，在拓宽半导体聚合物可实现的纳米形态谱方面具有相当大的前景，特别是在电子学或光伏领域的应用中。
